Defendant-Appellant Craig Rihl was convicted on one count of possession with intent to deliver marijuana, and one count of possession with intent to deliver hashish. 1 He was sentenced to two years in *1049 prison and fined $1,000 on each count, the sentences to run consecutively. Four issues have been presented for consideration on appeal:
1) Did the trial court err in admitting evidence seized during a warrantless search and arrest, conducted as a result of information supplied by an informant? 2
2) Did the trial court commit error in overruling Rihl’s pre-trial Motion to Compel Discovery as to certain interrogatories pertaining to a “confidential reliable informant” mentioned by the State during the suppression hearing?
3) Did the trial court err in overruling Rihl’s pre-trial Motion to Dismiss based upon a written agreement between Rihl and the arresting officers?
4) Did the trial court commit error in imposing consecutive sentences?
We affirm the conviction but remand to correct an error in sentencing.
I.
Rihl contends the trial court erred when it admitted into evidence the marijuana and hashish seized during a warrantless search and arrest. This contention is premised upon two arguments: 1) the State failed to show the reliability of its informant and therefore lacked probable cause to search; and 2) the police failed to demonstrate exigent circumstances to justify the warrant-less search of Rihl and his subsequent war-rantless arrest.
A warrantless search can only be justified by probable cause
and
one of the recognized exceptions to the warrant requirement.
Coolidge v. New Hampshire
(1971)
The record discloses that on the afternoon of Friday, August 12, 1977, Officer Gary Cook introduced Detective Charles Stanley to an informant who had agreed to set up a “buy” from Rihl. During a subsequent interview at the Hamilton County jail where the informant was a temporary resident, Stanley learned from the informant that he had purchased drugs from Rihl in the past. The informant also explained the usual procedure for the purchases in some detail:
“Q. You said, I think, earlier on direct, something about . .. you then talked with him about the Defendant and you talked to him about his selling habits and things like that,
A. Yes, sir.
Q. Why don’t you expand a little bit on that to the Court, what did you talk to him about? This is [the informant],
*1050 A. All right. I asked [the informant] to explain to me what procedure was taken when the purchase of marijuana or hashish would take place from Mr. Rihl. And he advised me that he would call ahead and that Mr. Rihl would meet him on Eller Road, south of 116th Street. He’d either be on foot or on his bicycle and that he would have a blue denim bag, which he wore around his neck, with the marijuana and hashish in it.
Q. In other words, whatever he ordered?
A. Right.
Q. In the denim bag?
A. Yes, sir.”
At about 3:30 p. m. Stanley took the informant and Cook to his office where the informant called Rihl to set up the buy. Stanley left the room during the call, but Cook remained to monitor one side of the conversation. At the hearing Cook testified the call opened “ ‘Yeah Craig, this is . .. ’ ” He also testified he heard the informant state, apparently in response to a question from Rihl, “ ‘Well, I need a couple bags of marijuana and I need an ounce of hash’ ”.
Before proceeding with the buy Stanley and Cook searched both the informant and his car; no drugs were found. The officers then followed the informant in an unmarked patrol car to Eller Road, just south of 116th Street. Rihl was waiting to be picked up at the exact point previously identified by the informant. Officer Cook testified the blue denim bag containing the marijuana and hashish was strapped over Rihl’s head. Rihl entered the informant’s car which was stopped after it had traveled a short distance, Rihl was searched, and the marijuana and hashish were found in the blue denim bag hanging around his neck. Rihl’s warrantless arrest followed.
A.
Probable Cause
Probable cause to search can be, and often is, based upon an informant’s tip. As a general rule, however, the informant’s reliability must be established before a probable cause determination can be made.
4
Reliability can be demonstrated by either showing a past record of reliability or by verification of extrinsic facts which indicate the informer’s information is trustworthy.
Pawloski
v.
State, supra,
While there is no evidence in the Record to support a finding of reliability based on past “track record”, there is ample evidence to support such a finding under the verification method. The informant here provided an explicit, detailed description of the buy procedure, complete with reference to the pick-up point and the blue denim bag which would contain the marijuana and hashish. The informant also made a telephone call to set up the buy in the presence of one of the arresting officers. As the facts show, each and every detail of the informant’s information was corroborated by the officers’ own observations. This step-by-step verification more than adequately substantiates the informant’s reliability and there can be no doubt his information was sufficient, once corroborated, to provide the officers with probable cause to search.
See Payne v. State
(3d Dist.1976)
*1051 B.
Warrantless Search
It is well settled that a search warrant is a condition precedent to a valid search and seizure except where the exigencies of the situation mandate an immediate response.
Ludlow v. State, supra,
The evidence shows the transaction involved here was the sale of controlled substances, always a potentially volatile situation regardless of the precautions taken. The evidence also shows the sale was to take place in an automobile, and that Rihl was riding in the automobile immediately prior to the search. It is axiomatic that exigent circumstances to justify an on-the-spot response by law enforcement officers are implied from the involvement of an automobile in the perpetration of a crime.
5
This implication is justified by the inherent mobility of an automobile and its potential to easily remove both the defendant and the evidence from the jurisdiction. As recently stated by our Supreme Court: “Given the public nature of automobile travel and the inherent mobility of automobiles, rigorous enforcement of the warrant requirement is not necessary.”
Rogers v. State
(1979) Ind.,
Given the potential dangers of the situation, a controlled substance sale, coupled with the exigent circumstances involving the automobile, we must conclude that the State sustained its burden of showing the existence of an exception to the warrant requirement. 6 We can find no error in the trial court’s evidentiary ruling.
II.
Rihl next contends the trial court erred in overruling his Motion to Compel Discovery, i. e., certain interrogatories sought to be propounded to the State dealing with the identity and reliability of a second “confidential reliable informant.” Rihl asserts the State bolstered its case by referring to this second informant during the suppression hearing, and relies on
Glover v. State
(1969)
The confidential-reliable informant question arose during the suppression hearing when Detective Stanley was questioned by the prosecutor concerning the first informant’s credibility:
“Q. Did you do anything or did you hear anything to establish [the first informant] as a credible individual concerning the information he was giving you?
A. Yes, sir, the information he was giving me I have heard in the past.
Q. From who?
*1052 A. Another confidential reliable informant that deals with me in narcotic traffic.
Q. Have you received from this other individual, have you received information that you’ve proved to be true in the past?
A. Yes, sir, many times.
Q. Have you gotten any convictions?
A. Not at this time. I’m expecting some.
Q. But you have checked out this other individual thoroughly?
A. Yes, sir.
Q. And that individual has proven to be truthful?
A. Yes, sir.
Q. And his story matched that of [the first informant]?
A. Yes, sir.”
The general policy in Indiana favors nondisclosure of criminal informants unless disclosure is relevant and helpful to the defense or is essential to a fair trial.
McCulley v. State
(1971)
Rihl’s reliance upon
Glover v. State, supra,
is misplaced. In
Glover
an officer testified at trial, before the jury, that an informant supplied the essential link in identifying the defendant as the guilty party. The Court specifically noted that, “this is not one of the rather common cases in which a defendant seeks to find out in preparing his defense preliminary to trial, the name of informers ... but rather [this case involves] the inherent right of a defendant to attack the probative value of the testimony and the credibility of a witness.”
In this light it is clear that the confidential reliable informant played no relevant or material part in Rihl’s search and arrest. Rihl has thus failed to make a showing that disclosure of this informant’s identity, or other personal information, would be helpful in preparing his defense or essential to a fair determination of the case.
See Lewandowski v. State, supra,
III.
Rihl’s third contention is that the trial court erred by denying his Motion to Dismiss Counts III (possession with intent to deliver marijuana) and IV (possession with intent to deliver hashish) of the information filed against him. Rihl claims he entered into an agreement with the arresting officers which granted immunity from prosecution for these charges. Essentially two arguments are forwarded in support of this claim of immunity: first, public policy considerations require the State to stand by the agreement; and second, any ambiguity should be strictly construed against the State. Both of these contentions are merit-less.
On the evening of his arrest, August 12, 1977, while being held in the Hamilton County Jail on informal charges of possession of marijuana and possession of hashish, Rihl entered into the following “agreement” with Detective Stanley and Deputy Cook:
*1053 “It is agreed that if Craig D. Rihl takes Deputy G. Cook and Dect. Sgt. C. P. Stanley to his home located 6240 E. 116th St. Nobles, Ind. and turns over any controlled substance such as marijuana, hashish, or any other narcotic drug found at that location he will not be charged with any other criminal offense except those charged before 6:00 O’Clock p. m. 8-12-77
/s/ Dect. Sgt. C. P. Stanley
/s/ Gary A. Cook”
Formal charges were filed against Rihl on August 15, 1977. The two-count information consisted of one count charging possession of marijuana, and one count charging possession of hashish. A second information adding counts III and IV, for which Rihl was subsequently convicted, was filed on November 28, 1977. The offenses alleged in counts III and IV have greater potential penalties than those alleged in counts I and II.
In denying Rihl’s Motion to Dismiss, the trial court construed the second use of the word “charged” in the agreement to mean “chargeable”, found the substance of the agreement to be that no charges would arise from the controlled substances found at Rihl’s home, noted no such charges had been filed, and entered an order on its own motion prohibiting any reference during trial to the agreement or what was found in Rihl’s home.
In support of his public policy argument Rihl relies upon authorities with little, if any, relevance to this case. Each of the cases cited involved at least three factors not present here: 1) the involvement of the prosecutor; 2) at least nominal approval by the court; and 3) some detriment to the defendant by the State’s failure to abide by its bargain.
Butler v. Florida
(Fla.App. 1969)
It is also apparent that the trial court correctly construed the writing signed by Stanley and Cook. The substance of the agreement, ascertainable from the language used, is that Rihl would incur no criminal liability for the drugs found at his home. The construction Rihl supports is not only contrary to the more reasonable *1054 interpretation but would also lead to absurd results. Since Rihl was not charged with anything until August 15, 1977, all criminal charges would have to be dismissed. Read literally the construction sought by Rihl would grant permanent absolution for all future sins against society in return for one not-so-unselfish act.
We find no error in the trial court’s denial of Rihl’s motion to dismiss.
The judgment is affirmed.
IV.
Rihl’s final contention is that the trial court erred in imposing consecutive sentences. We agree, and remand this case to the Hamilton Circuit Court for action consistent with this section of our opinion. 9
It is the law in Indiana that consecutive sentencing is not proper unless specifically authorized by statute.
Hawkins v. Jenkins
(1978)
Rihl’s conviction is affirmed, but the case is remanded so that the error in sentencing can be corrected.
Notes
. I.C. 35-24.1 — 4.1-10(a)(2) (repealed Oct. 1, 1977) (current version at I.C. 35-48-4-10 (Bums Code Ed. Supp.1980)).
. Although Rihl couches his argument in terms of the ruling on his Motion to Suppress, objections to the admission of the evidence itself were made at trial in the form of specific incorporation of the objections made at the suppression hearing. The alleged error has therefore been preserved upon appeal.
See Norton v. State
(1980) Ind.,
. This is the recognized standard for a probable cause affidavit presented to a magistrate, but it applies with equal force to the. present situation.
State v.
Mooney (4th Dist.1979) Ind.App.,
. Rihl does not challenge the accuracy or sufficiency of the basic facts supplied by the informant. Such a challenge, at any rate, would be meritless given the details provided by the informant and their verification by the officers.
. Rihl relies heavily on statements made by Stanley and Cook during the suppression hearing which tend to negate a finding of exigent circumstances. The subjective impressions and evaluations of the officers, however, cannot overcome the realities of the situation.
Taylor v. State
(1980) Ind.,
. These same circumstances justify Rihl’s war-rantless arrest after the marijuana and hashish were found in his possession.
Pawloski v. State, supra,
. The authority of police officers to enter into a binding agreement or to grant immunity is not before us.
But see State ex rel. Spencer v. Criminal Court of Marion County
(1938)
. It is this lack of detriment to the defendant which also distinguishes this case from
Ashby v. State
(1976)
. The State argues this allegation of error was waived by Rihl’s failure to object at the time of sentencing. It is well settled that a sentencing error may be raised for the first time on appeal.
Lewandowski v. State, supra,
. I.C. 35-50-1-2 (Bums Code Ed. 1979) (effective Oct. 1, 1977), provides:
“Consecutive and concurrent terms.-(a) Except as provided in subsection (b) of this section, the court shall determine whether terms of imprisonment shall be served concurrently or consecutively.
(b) If a person commits a crime:
(1) After having been arrested for another crime; and
(2) Before the date he is discharged from probation, parole, or a term of imprisonment imposed for that other crime;
the terms of imprisonment for the crimes shall be served consecutively, regardless of the order in which the crimes are tried and sentences are imposed.”
