¶ 1 Appellant Ronald L. D’Collanfield appeals his judgment of sentence entered on September 21, 2001, in the Court of Common Pleas of Lehigh County. On that date, Appellant pleaded guilty to one count of stalking by communication or address, in violation of 18 Pa.C.S.A. § 5504(a.l)(2). Pursuant to a negotiated plea agreement, Appellant was sentenced to three years probation. Upon review, we affirm.
¶2 The relevant facts and procedural history are as follows: In January, 2001, Appellant received a court-ordered psychological evaluation for a separate criminal incident. Frank Dattilio, Ph.D., performed the evaluation. Following the evaluation, Appellant began to send Dr. Dattilio “bizarre” E-mails. Between January, 2001, and March, 2001, Appellant sent Dr. Dattilio nine such E-mails. On March 14, 2001, Detective Louis Tallarico of the Allentown Police Department arrested Appellant and charged him with one count of stalking by communication, in violation of 18 Pa.C.S.A. § 5504(a.l)(2), and one count of harassment by communication, in violation of 18 Pa.C.S.A. § 5504(a)(4). A preliminary hearing was held on April 10, 2001. At that time, all charges were waived into the Court of Common Pleas of Lehigh County. On September 21, 2001, pursuant to a negotiated plea agreement, Appellant pleaded guilty to one count of stalking in violation of 18 Pa.C.S.A. § 5504(a.l)(2). On October 22, 2001, Appellant filed a timely notice of appeal pro se. Thereafter, on November 2, 2001, Appellant’s plea counsel withdrew from his representation. New counsel was retained on December 5, 2001. The sentencing *1246 court ordered a Pa.R.A.P. 1925(b) concise statement of matters complained of on appeal. Appellant complied with this order and filed the Pa.R.A.P. 1925(b) statement on December 28, 2001. The sentencing court filed its Pa.R.A.P. 1925(a) opinion on January 18, 2002.
¶ 3 Appellant presents two questions for our review:
(1) Did the [trial] court err in [accepting] a guilty plea where the evidence presented at the plea was insufficient to establish guilt beyond a reasonable doubt?
(2) Was trial counsel ineffective for advising [Appellant] to plead guilty where there was insufficient evidence presented to establish guilt beyond a reasonable doubt?
Appellant’s brief, at vi.
¶ 4 Initially, we note that Appellant has failed to challenge his guilty plea via an optional post-sentence motion. The comment to Pa.R.Crim.P. 720 states, in relevant part:
A post-sentence challenge to a guilty plea under this rule is distinct from a motion to withdraw a guilty plea prior to sentence. See Rule 591. Cf. Standards Relating to Pleas of guilty § 2.1(a)(ii), ABA PROJECT ON MINIMUM STANDARDS FOR CRIMINAL JUSTICE (Approved Draft, 1968). Properly preserved issues related to guilty pleas need not be raised again in the post-sentence motion, but the defendant may choose to do so. A key consideration for the defendant is whether the record will be adequate for appellate review. If counsel is uncertain about the record, it is recommended that the guilty plea be challenged in the post-sentence motion.
¶ 5 After a review of the record, we conclude that Appellant’s first issue was not properly preserved for appeal because trial counsel failed to preserve the issue by objecting at the sentence colloquy or otherwise raising the issue at the sentencing heai'ing or through a post-sentence motion.
See
Pa.R.Crim.P. 720(B). Accordingly, we find Appellant’s first issue waived for purposes of appeal.
See Commonwealth v. Archer,
¶ 6 Our standard of review in ineffectiveness cases is well-settled. Counsel is presumed effective, and the appellant has the burden of proving otherwise.
Commonwealth v. Carson,
¶ 7 Our first prong of analysis in an ineffective assistance case is to determine whether Appellant’s underlying claim is of arguable merit. In determining whether Appellant’s claim has arguable merit, we must first look to the standard applied in withdraw of guilty plea cases. When considering a petition to withdraw a plea submitted to a trial court after sentencing, it is well-established that a showing of prejudice on the order of manifest injustice is required before withdrawal is properly justified. Comm
onwealth v. Shaffer,
¶ 8 In order to make this determination, we first look to the statutory provisions of the crime of stalking by communication, found in 18 Pa.C.S.A. § 5504(a.l). Title 18 Pa.C.S.A. § 5504(a.l) states, in pertinent part:
(a.l) Stalking by communication or address. — A person commits the crime of stalking by communication or address when the person engages in a course of conduct or repeatedly communicates either of the following:
(1) An intent to place such other person in reasonable fear of bodily injury.
(2) An intent to cause substantial emotional distress to such other person. 2
¶ 9 At Appellant’s plea hearing, the Commonwealth stated that it would have introduced the following facts to prove the charge of stalking by communication had the case gone to trial:
MR. SHORE: Judge, if Detective Tal-larico of the Allentown Police were called to testify, he would state that the defendant received a court ordered evaluation by Dr. Frank Datti-lio in January 2001.
Since that point, since receiving Dr. Dattilio’s diagnosis of him, the defendant had began sending several Email communications with Dr. Dattilio, nine in total, beginning in January of 2001 and continuing through March— the middle of March of 2001.
*1248 These emails were harassing and frankly a bit bizarre in nature, and they did cause Dr. Dattilio a great amount of concern and alarm.
N.T. Sentencing Hearing, 9/21/2001, at 4-5.
¶ 10 After the Commonwealth presented the above facts, the sentencing court questioned Appellant as follows:
THE COURT: All right. Well, Mr. D’Collanfield, do you have any recollection of sending these things to Dr. Dattilio?
APPELLANT: Yes, I sent—
THE COURT: Something to him?
APPELLANT: I sent the E-mail. Although it should be pointed out that he sent me an E-mail on March the 6th inviting me to come into his office to get a copy of the psychological evaluation so it’s rather strange all the way around.
THE COURT: Do you remember the content of the E-mails that you sent to him?
APPELLANT: I admit that what I was sending him didn’t make any sense when you look at it from the whole picture. The judge had ordered that I receive intensive treatment. He had called — he had labeled me a paranoid schizophrenic.
I was shocked at that. I was — he didn’t take the time to explain why he came to that, why he arrived at that diagnosis. So I was enraged. I admit that I was out of control. I should not have sent this E-mail. Had I known there was a law against it, I certainly would not have sent it. Ironically, he’s the only psychologist in the area who has a website, and therefore, an E-mail address.
N.T. Sentencing Hearing, 9/21/2001, at 5-6.
¶ 11 In our determination of whether the facts provided by the Commonwealth were sufficient to form a factual basis for Appellant’s guilty plea to stalking by communication, we note that the appellate courts of this Commonwealth have not yet had an opportunity to analyze 18 Pa. C.S.A. § 5504(a.l). Therefore, we feel it necessary to analyze caselaw pertaining to the stalking statute present in 18 Pa. C.S.A. § 2709(b). Title 18 Pa.C.S.A. § 2709(b) states, in pertinent part:
(b) Stalking. — A person commits the crime of stalking when he engages in a course of conduct or repeatedly commits acts toward another person, including following the person without proper authority, under circumstances which demonstrate either of the following:
(1) An intent to place the person in reasonable fear of bodily injury; or
(2) An intent to cause substantial emotional distress to the person.
¶ 12 It is clear that the two statutes, 18 Pa.C.S.A. § 5504(a.l) and 18 Pa.C.SA. § 2709(b), are virtually identical. The only difference between the two crimes is that the course of conduct prohibited by 18 Pa.C.S.A. § 5504(a.l) takes place via some method of communication, either written or electronic. See 18 Pa.C.S.A. § 5504(a.l).
¶ 13 The first element of the crimes of stalking and stalking by communication is engaging in a course of repetitive conduct. A course of conduct is established by proof of two related but separate events.
Commonwealth v. Leach,
¶ 14 In
Commonwealth v. Reese,
¶ 15 We are convinced that this evidence was sufficient to indicate to the trial court that Appellant intended to cause substantial emotional distress to the victim. It is clear that simply because Appellant did not state specifically that he wished to cause “great concern and alarm” or “substantial emotional distress” to Dr. Dattilio that he did not intend to do so. We have held consistently that intent may be inferred from the words or actions of the defendant in light of all attendant circumstances.
Commonwealth v. Pasley,
*1250 ¶ 16 Therefore, we find that Appellant’s claim of counsel’s ineffectiveness is without arguable merit and affirm his judgment of sentence.
¶ 17 Judgment of sentence affirmed.
Notes
. Our Supreme Court has held that to satisfy the requirements of Pa.R.Crim.P. 590, the trial court must inquire, at a minimum, the following:
(1) Does the defendant understand the nature of the charges to which he or she is pleading guilty or nolo contendere?
(2) Is there a factual basis for the plea?
(3) Does the defendant understand that he/ she has the right to a trial by jury?
(4) Does the defendant understand that he/ she is presumed innocent until found guilty?
(5) Is the defendant aware of the permissible range of sentences and/or fines for the offenses charged?
(6)Is the defendant aware that the judge is not bound by the terms of any plea agreement tendered unless the judge accepts such agreement?
Commonwealth v. Anthony,
Appellant only challenges the factual basis for his plea. Therefore, we will confine our analysis to that issue.
. Title 18 Pa.C.S.A. § 5504(a.l) defines "emotional distress” as, "[a] temporary or permanent state of mental anguish.”
. We are satisfied that "great concern and alarm” is the type of mental anguish contemplated by both stalking statutes.
See Commonwealth v. Roefaro,
. We also note that Appellant executed a written plea colloquy in addition to the on-the-record colloquy with the court. The written colloquy questioned him if he knew what crime was charged against him, and whether his attorney explained the elements of the crime to which he was pleading guilty. Written plea colloquy, at 2. Appellant answered "yes” to both questions.
Id.
at 2. We will not allow Appellant to claim that he lied with respect to the answers made at his guilty plea colloquy and in his written colloquy.
