PHOENIX – Phoenix police have arrested a third person and are looking for a fourth suspect in connection with the investigation into an armed robbery and attempted homicide of an officer and a Maricopa County Sheriff's Office posse member.

Jason Beau Keep, 35, was charged with conspiracy to commit armed robbery.

According to court documents, Keep was fired from the Pink Rhino Cabaret just before Christmas and decided to get back at his former employer by robbing the business. After that robbery, one of his alleged cohorts shot the Phoenix police officer and posse member during their botched getaway.

Keep was a forward for Oklahoma State University and was once an aspiring NBA player but was never drafted. He played in several international leagues and was still active in athletic circles in the Valley.

Phoenix police Sgt. Tommy Thompson said detectives are still looking for William Herbert Mayes, 30. Police are not saying how he was involved, only that he is a suspect in the case.

Thompson said numerous Silent Witness billboards around the Valley have gone up with Mayes' information.

Police arrested two other suspects earlier this week. Roger Allen Sharp Jr., 26, and David Lee Murray Jr., 36, were taken into custody Tuesday afternoon.

According to police, Sharp and Murray were involved in the armed robbery of two employees of the Pink Rhino in the parking lot of an IHOP restaurant near 44th Street and Thomas Road. The employees were carrying $18,000 of the strip club's money at the time.

The suspects fled in a maroon Chevy Impala and collided with the posse member's truck at 56th Street and Thomas Road during a pursuit by police.

Sharp allegedly shot Phoenix police Officer Scott Sefranka and the posse member with the officer's gun during a struggle.

Sharp and Murray were found in separate backyards near the scene.

Both shooting victims were critically wounded. Sefranka is showing signs of improvement following two surgeries. There is no update on the posse member's condition.

Anyone who knows the whereabouts of Mayes is asked to contact the Phoenix Police Department Violent Crimes Bureau at 602-262-6141 or Silent Witness at 480-WITNESS or 480-TESTIGO for Spanish.
