The Commonwealth of Pennsylvania appeals from the Order denying its Motion in Limine to introduce Facebook posts and messages allegedly authored by defendant Tyler Kristian Mangel ("Mangel"). We affirm.
On June 26, 2016, Nathan Cornell ("Cornell") was assaulted at a graduation party. On July 15, 2016, a Criminal Complaint was filed against Mangel, at CR 2939 of 2016, charging him with aggravated assault, simple assault and harassment of Cornell. See 18 Pa.C.S.A. §§ 2702(a)(1), 2701(a)(1), 2709(a)(1). At CR 2940 of 2016, the Commonwealth filed a separate Criminal Complaint against Matthew Robert Craft ("Craft"), charging him with the same offenses. The criminal cases against Mangel and Craft were consolidated for trial. Attached to the Criminal Complaints was an Affidavit of Probable Cause,
On March 15, 2017, the Commonwealth filed a Motion for Provider to Provide Subscriber Information, pursuant to
On May 8, 2017, the trial court conducted a hearing on the Motion, at which the Commonwealth presented the testimony of Erie County Detective Anne Styn ("Detective Styn"), whom the trial court qualified as an expert in computer forensics. N.T., 5/8/17, at 7. Detective Styn testified that she had received a request from the Commonwealth to determine the owner of a particular Facebook account, bearing the name "Tyler Mangel," and was provided with "Facebook screenshots captured from online, as well as mobile device chats" of that account taken by Trooper Schaeffer
Detective Styn then "conducted a search on Facebook for the individual's name, Tyler Mangel, in which only one name had populated at that time [as] being [']Tyler Mangel.[']" N.T., 5/8/17, at 9. Detective Styn then compared the Facebook account that she had located to the screenshots that she had received from the Commonwealth, and noticed that both the screenshots and the Facebook account bore name "Tyler Mangel;" both listed the account holder as living in Meadville, Pennsylvania; and some of the photographs on the screenshots were the same as those on the Facebook account.
Detective Styn then compared the Facebook account that she had located to the screenshots provided to her by the Commonwealth, and came to the conclusion that the Facebook account that she had located "should be the same" as the account in the screenshots provided by the Commonwealth because both accounts (1)
*1157bore the name "Tyler Mangel;" (2) listed the account holder as living in Meadville, Pennsylvania; (3) listed the account holder as having attended Meadville High School; and (4) displayed several photographs which seemed to be of the same individual.
The Court: Well, I'm the gatekeeper of admissibility. So[,] I want to know, first of all, can you even testify to a reasonable degree of computer and scientific certainty the answer to that question? I mean, can you do that? And[,] this is a criminal case. This is not probability. This is certainty and you know what that is.
[Detective] Styn: Correct.
The Court: So, can you do that, first of all?
[Detective] Styn: Based on my training and experience, in this particular instance I would solely base my testimony off the records that I received from Facebook and Verizon.
The Court: And could you do that with a reasonable degree of certainty that it was what? [ ] Mangel that did all of this?
[Detective] Styn: That this account was registered under Tyler Mangel's account and-
The Court: No. That [ ] Mangel actually did this. You can do that with a reasonable degree of certainty? You can say that he did this? That no one else intervened or someone else grabbed the account? You can do that?
[Detective] Styn: I cannot, Judge.
The Court: So, objection sustained.
*1158On May 9, 2017, the Commonwealth timely filed a joint Notice of Appeal, pursuant to Pa.R.A.P. 311(d), claiming that the trial court's Order denying its Motion in Limine terminated or substantially handicapped the prosecution of its criminal cases against Mangel and Craft. The Commonwealth thereafter filed a joint court-ordered Pa.R.A.P. 1925(b) Concise Statement of matters complained of on appeal.
On appeal, the Commonwealth raises the following issues for our review:
1. Did the trial court commit legal error when it applied a "reasonable degree of scientific certainty" standard in determining whether [the Commonwealth] provided adequate extrinsic evidence to support the authenticity of Facebook records?
2. Did the trial court commit legal error when it failed to apply "whether the jury could reasonably find the authenticity of the Facebook records by a preponderance of the evidence" standard in determining whether [the Commonwealth] provided adequate extrinsic evidence to support the authenticity of the Facebook records?
Brief for the Commonwealth at 3 (capitalization omitted).
The Commonwealth claims that the trial court erred by applying "a reasonable degree of certainty, reliability, scientific, technological certainty" standard in determining whether the Commonwealth had satisfied the requirements for authentication of the proffered Facebook records.
Our standard of review of a denial of a motion in limine is as follows:
When ruling on a trial court's decision to grant or deny a motion in limine , we apply an evidentiary abuse of discretion standard of review. The admission of evidence is committed to the sound discretion of the trial court, and a trial court's ruling regarding the admission of evidence will not be disturbed on appeal unless that ruling reflects manifest unreasonableness, or partiality, prejudice, bias, or ill-will, or such lack of support to be clearly erroneous.
Commonwealth v. Moser ,
Pursuant to Pennsylvania Rule of Evidence 901, authentication is required *1159prior to admission of evidence. The proponent of the evidence must introduce sufficient evidence that the matter is what it purports to be. See Pa.R.E. 901(a). Testimony of a witness with personal knowledge that a matter is what it is claimed to be can be sufficient. See Pa.R.E. 901(b)(1). Evidence that cannot be authenticated by a knowledgeable person, pursuant to subsection (b)(1), may be authenticated by other parts of subsection (b), including circumstantial evidence pursuant to subsection (b)(4).
The question of what proof is necessary to authenticate social media evidence, such as Facebook postings and communications, appears to be an issue of first impression in Pennsylvania. Facebook is a social networking site where "[u]sers of that Web site may post items on their Facebook page that are accessible to other users, including Facebook 'friends' who are notified when new content is posted." Nicolaou v. Martin ,
Pennsylvania appellate courts have considered the authentication of computerized instant messages and cell phone text messages. See In the Interest of F.P., a Minor ,
Notably, the In re F.P. Court rejected the argument that electronic communications, such as text messages or e-mails, are inherently unreliable due to their relative anonymity and the difficulty connecting them to their author, noting that the same uncertainties exist with written documents: "[a] signature can be forged; a letter can be typed on another's typewriter; distinct letterhead stationary can be copied or stolen." In re F.P. ,
In Koch , this Court examined whether cell phone text messages had been appropriately authenticated prior to their admission into evidence. In that case, the Commonwealth sought the admission of text messages retrieved from a cell phone taken during the execution of a search warrant on the defendant's residence. Koch ,
The Koch Court looked to this Court's prior holding in In re F.P. , as well as cases from other jurisdictions wherein courts had examined the authentication of text messages, and concluded that "[i]mplicit in these decisions is the realization that e-mails and text messages are documents and subject to the same requirements for authenticity as non-electronic documents generally. Koch ,
However, the Koch Court was mindful of the various challenges presented in authenticating electronic communications:
[T]he difficulty that frequently arises in e-mail and text message cases is establishing authorship. Often more than one person uses an e-mail address and accounts can be accessed without permission. In the majority of courts to have considered the question, the mere fact that an e-mail bears a particular e-mail address is inadequate to authenticate the identity of the author; typically, courts demand additional evidence.
Applying these considerations to the evidence in the record, the Koch Court concluded that the testimony of the detective was insufficient to authenticate the text messages in question, noting that there was no testimony from any person who had sent or received the text messages, nor any contextual clues in the drug-related text messages that tended to reveal the identity of the sender.
Recently, in Browne , the United States Court of Appeals for the Third Circuit addressed the authentication of Facebook chat logs, and concluded that "it is no less proper to consider a wide range of evidence for the authentication of social media records than it is for more traditional documentary evidence[,]" and that "the Rules of Evidence provide the courts with the appropriate framework within which to conduct that analysis." Browne ,
In concluding that the Facebook records were properly authenticated under F.R.E. 901,
In our view, the same authorship concerns, as expressed by the Koch Court in relation to e-mails and instant messages, exist in reference to Facebook and other social media platforms, that can be accessed from any computer or smart phone with the appropriate user identification and password. See Koch ,
*1163Griffin v. State ,
Turning to the record before us, the trial court, in reliance upon Koch , explained that it had denied the Commonwealth's Motion in Limine on the basis that it had failed to present sufficient evidence that tended to corroborate that Mangel was the sender of the Facebook communications in question. See Trial Court Opinion, 7/10/17, at 9. As explained by the trial court,
... Mangel did not himself state at any time that the Facebook account in question was his own personal Facebook account and/or that he authored the posts and messages on the Facebook account, and the Commonwealth did not introduce subsequent testimony from any other knowledgeable party to substantiate that the Facebook page (and, by association, the posts and messages contained therein) belonged to [ ] Mangel. Moreover, the Commonwealth did not obtain the username or password for the Facebook account to confirm its authenticity. Although the Commonwealth did produce evidence allegedly linking [ ] Mangel to the Facebook page in question, including a name, hometown, school district and certain pictures, this information has generally been held to be insufficient to connect a defendant to posts and messages authored on a Facebook page. In fact, following a search on Facebook for the name of "Tyler Mangel" by [defense counsel], five (5) "Tyler Mangel" Facebook accounts appeared in response to the search, one of which has the same hometown of "Meadeville, Pennsylvania," which contradicts Detective Styn's testimony that only one (1) "Tyler Mangel" Facebook account appeared during her search.
A thorough review of the Facebook posts and messages themselves raises specific issues. First, the evidence presented by the Commonwealth does not indicate the exact time the posts and messages were made. The incident which brought about the instant criminal charges occurred allegedly on June 26th, 2016, according to the Criminal Information. The lack of a date and timestamps raises a significant question regarding the connection of the posts and messages to the alleged incident on June 26th, 2016. Furthermore, the "Tyler Mangel" who allegedly authored the Facebook posts and messages does not specifically reference himself in the incident on June 26th, 2016; rather, other individuals, many of them who are not directly involved in the instant criminal case, reference a "Tyler Mangel" in response to a post made and in subsequent conversations about an alleged assault. Moreover, the Facebook posts and messages are very ambiguous, containing slang and other nonsensical words with "Like" replies, and do not specifically *1164and directly relate to the alleged incident on June 26th, 2016. Finally, the Commonwealth did not produce evidence as to the distinct characteristics of the posts and messages which would indicate [that] Mangel was the author.
Also, as part of the Commonwealth's Exhibit 2, the Commonwealth introduced a black and white copy of a Facebook picture of a hand, which is allegedly bloody and bruised. However, this picture was posted by a Facebook user named "Justin Jay Sprejum Hunt," who makes no reference to [ ] Mangel or Craft. Therefore, this Facebook exhibit offered by the Commonwealth is not relevant regarding the authentication of the Facebook posts and messages.
Trial Court Opinion, 7/10/17, at 9-10 (internal citations and footnote omitted).
Based on its explanation, it is clear that the trial court, in recognizing Koch as the controlling legal precedent in Pennsylvania for the authentication of electronic communications, applied the proper standard in determining whether the Commonwealth had presented sufficient direct or circumstantial evidence that Mangel had authored the Facebook messages in question.
Order affirmed.
Notes
The Affidavit of Probable Cause attached to each Criminal Complaint was the same, except for the docket number, OTN number and the defendant's name.
Trooper Schaeffer's first name is not contained within the record.
Notably, Detective Styn had testified that an investigation of social media includes retrieving IP addresses to determine the specific location from which an item has been posted, including the specific computer or network where a particular post originated from. See N.T., 5/8/17, at 5-6, 23.
This Court, sua sponte , consolidated the appeals.
Although the Commonwealth purports to raise two issues on appeal, the Argument section of its brief contains only one section. See Pa.R.A.P. 2119(a) (providing that "[t]he argument shall be divided into as many parts as there are questions to be argued; and shall have at the head of each part-in distinctive type or in type distinctively displayed-the particular point treated therein."). Nevertheless, as the Commonwealth's issues are related, we will address them together.
Pursuant to Rule 901(b)(4), evidence may be authenticated by "Distinctive Characteristics and the Like. The appearance, contents, substance, internal patterns, or other distinctive characteristics of the item, taken together with all the circumstances." Pa.R.E. 901(b)(4).
Because an equally divided Supreme Court affirmed this Court's grant of a new trial in Koch , our Supreme Court's decision is not binding in this case. See Commonwealth v. Mosley ,
In In re F.P . , the Court noted that "[t]here is a paucity of cases involving authentication of e-mails or instant messages, none in the Commonwealth of Pennsylvania." Based on our review, it appears that there have been no further intermediate court developments in the specific area of authentication of social media evidence since the In re F.P. Opinion was published.
Also at issue in Koch was whether the text messages constituted inadmissible hearsay under Pa.R.E. 802. See Koch ,
Pa.R.E. 901 is substantially identical to F.R.E. 901. See Pa.R.E. 901, cmt. Relevant to this analysis, Pa.R.E. 901(b)(4) is identical to F.R.E. 901(b)(4). See
We further observe that the Commonwealth did not produce any evidence that Mangel had created, or had access to, the email accounts associated with the Facebook account (mangel17@facebook and tylertkm@hotmail.com), per the Facebook subscriber records. Nor did the Commonwealth produce any evidence that Mangel had access the cellular phone with the number (814) 573-4409, associated with the Facebook account, or any relationship with the individual who owned that number ("Stacy Mangel").
The Commonwealth appears to conflate the authentication of evidence standard applied by the trial court, with the expert testimonial standard employed during the trial court's questioning of Detective Styn. As Detective Styn had been qualified as an expert, the trial court properly inquired whether she could state her opinions with a reasonable degree of certainty. See Commonwealth v. Gonzalez ,
