OPINION
Derrick Mack challenges his conviction after a jury trial of dealing in cocaine, 1 a Class A felony, and possession of cocaine, 2 a Class D felony. Although Mack raises three issues, we find one dis-positive: whether the State’s witness’ comment that he identified Mack out of a group of people known to deal drugs in the area where Mack was arrested subjected Mack to grave peril. 3
Reversed and remanded.
FACTS AND PROCEDURAL HISTORY
Detective Peter Perkins of the Indianapolis Police Department worked an undercover narcotics investigation on August 4, 1997, targeting the neighborhood of 2400 North Alabama Street. Detective Perkins saw five or six black males standing on the corner of 24th and Alabama Streets., He drove up and made eye contact with one of the males, later identified as Mack. Mack approached the undercover vehicle and put his finger to his lips, indicating that Detective Perkins was to remain silent. Mack held out a clear plastic bag containing crack cocaine, and Detective Perkins gave Mack $20.00. The transaction took approximately thirty seconds.
Detective Perkins then drove around the corner and radioed in a description of Mack. Although officers entered the area, they were unable to locate Mack. Approximately ten to fifteen minutes after the transaction, Detective Perkins met assist *803 ing officers, who showed him a photo array of twelve African-American males. Detective Perkins identified Mack with 100 percent certainty. (R. at 120, 127.) A warrant was issued for Mack’s arrest on September 8, 1997, although he was not arrested and arraigned until almost a year later.
At the trial, Detective Perkins was the only identification witness. He testified that he identified Mack after he was shown a 12-pack photograph of people known to deal in the area of 24th and Alabama. (R. at 104.)
DISCUSSION AND DECISION
The trial court erred when it denied Mack’s motion for mistrial after Detective Perkins’ reference to the pre-as-sembled photographic array. The trial court has discretion in determining whether to grant a mistrial, and its decision is afforded great deference on appeal because the trial court is in the best position to gauge the surrounding circumstances of the event and its impact on the jury.
Schlomer v. State,
Detective Perkins’ statement injected into trial the issue of Mack’s prior criminal conduct - specifically, that Mack was known to deal drugs in this particular area.

In considering whether this warranted the declaration of a mistrial, it is instructive to look at
Garcia v. State,
One White factor at issue in the present case is the other evidence of guilt. Officer *804 Perkins was the only witness who testified with respect to Mack’s identity. No other law enforcement officers observed the buy, there was no other evidence such as video or audiotape, and no buy-bust marked bills were recovered. As a result, the State’s case rested wholly upon Detective Perkins’ identification. Tied to this factor is the factor of the degree of materiality of the testimony. Detective Perkins’ identification of Mack as someone known to deal drugs in the area of the undercover drug buy was highly material.
The admission of evidence of Mack’s collateral criminal conduct was not harmless. Because there was no independent evidence of Mack’s guilt, there was a substantial likelihood that the evidence in question played a part in Mack’s conviction.
See James v. State,
The critical importance of Detective Perkins’ ability to identify Mack, in combination with the absence of corroborating evidence and the prejudice presumed from being labeled in front of the jury by the only identifying witness a known drug dealer, requires reversal.
Reversed.

. Mack also claims that the evidence was insufficient to sustain his convictions and that double jeopardy was violated by his convictions of dealing in cocaine and possession of cocaine. With respect to Mack's double jeopardy argument, we note that in
Richardson v. State,
. We wish to make clear that this is not a case of prosecutorial misconduct. The prosecutor in the present case did not intentionally elicit the officer’s testimony regarding Mack's prior criminal conduct.

listed thirteen factors bearing on the necessity of a mistrial. Those were 1) the effect of constitutional provisions, statutes or rules relating to harmless error; 2) the degree of materiality of the testimony; 3) other evidence of guilt; 4) other evidence tending to prove the same fact; 5) other evidence that may cure the improper testimony; 6) possible waiver by the injured party; 7) whether the statement was volunteered by the witness and whether there had been deliberate action on the part of the prosecution to present the matter to the jury; 8) the penalty assessed; 9) whether or not the testimony, although volunteered by the witness, was in part brought out by action of the defendant or his counsel; 10) the existence of other errors; 11) whether the question of guilt is close or clear and compelling; 12) the standing and experience of the person giving the objectionable testimony; and 13) whether or not the objectionable testimony or misconduct was repeated.
