Deputies from the Perris Sheriff’s Station began investigating last Wednesday’s robbery around 11:50 a.m., Riverside Sheriff’s Sergeant John Burke reported today.

During the initial investigation deputies learned the victim had used a social media website to make arrangements to sell something to the two suspects, according to Burke; who did not specify what was being offered for sale.

Due to the circumstances, deputies and investigators assigned to the station’s Robbery / Burglary Suppression Team immediately assumed the investigation 

“When all parties had arrived, the two suspects robbed the victims at gunpoint,” Burke explained; adding, “Within the first several hours of the investigation, Airron Deprese Willis of Moreno Valley and Diamond Crummie of Banning were identified as suspects.”

Based on their developed leads and gathered information, investigators, with assistance from members of the Sheriff’s Special Weapons and Tactics (SWAT) team, served a search warrant at a residence in the 23000 block of Brookhaven, in Moreno Valley.

“Both suspects had fled shortly before the service of the warrant, and warrants were issued for both suspects,” said Burke.

On the evening of July 9, Gang Impact Team members located and arrested Diamond Crummie on Sweeney Drive in the city of Moreno Valley. He was turned over to the Perris Station Burglary Suppression Team and subsequently booked into the Cois Byrd Detention Center in Murrieta on suspicion of robbery, criminal conspiracy and an unrelated shoplifting charge.

On July 13, Gang Impact Team members located and arrested Airron Willis on Indiana Avenue in the city of Riverside. He was turned over to the Perris Station Burglary Suppression Team and subsequently booked into the Cois Byrd Detention Center in Murrieta on suspicion of robbery, criminal conspiracy and violation of parole.

Online jail records indicate both men remain in custody, with Willis being held without bail and Crummie remaining in custody in lieu of $275,000 bail or bond. Both men were expected to be arraigned on their charges at Riverside Hall Of Justice today.
