Former star center Jason Keep arrested Friday

PHOENIX - Phoenix police arrested 35-year-old former University of San Diego basketball player Jason Keep in connection with a violent armed robbery on New Year's Eve that left a police officer and a volunteer sheriff's office posse member critically wounded.

Detectives arrested Keep on suspicion to commit armed robbery on Friday.

Police say that on Dec. 31, Roger Sharp and David Murray Jr. were involved in an armed robbery in a parking lot outside a strip club where they robbed two strip club employees of $18,000.

The robbery then led to a chase as an officer spotted the getaway car while responding to the armed robbery, police said.

Police say the suspects' car collided into a pickup truck driven by a civilian volunteer sheriff's office posse member.

Sharp, the driver of the suspects' car, got into a struggle with the officer, police said. The civilian sheriff member saw the struggle and attempted to assist the officer. 

Police say Sharp was able to take control of the officer's gun and used it to shoot both the officer and the man who came to his aid.

Both suspects then ran from the scene before being arrested by police.

Sharp was arrested on suspicion of attempted first-degree murder, armed robbery, burglary and other charges, while Murray was arrested on suspicion of armed robbery.

Officer Scott Sefranka, 34, remains in the hospital. He is listed in critical but stable condition.

Phillip Grigg, the volunteer posse member, is listed in critical condition. Grigg, 64, is a father of two, and a grandfather of three.

Phoenix police are still looking for a fourth suspect identified as 30-year-old William Mayes.
