(CBS/AP) DENVER - Rollin Oliver, a Colorado man, will face trial in the fatal shooting of Denver police officer Celena Hollis during a free jazz festival at City Park last summer.
A judge ruled Thursday there's enough evidence to put Oliver, 21, on trial in first-degree murder with extreme indifference in the death of Hollis, who was off duty but in uniform as she tried to break up a confrontation at the park on June 24.
Investigators said four bullets found at the scene were linked to a gun found with Oliver. William Drexler, Oliver's public defender, said shots were fired as Oliver left the park after suspected members of the Crips gang flashed gang signs.
He said Oliver purchased a gun after he was shot at a party in an unrelated incident.
