San Pablo police have arrested two people in connection with the fatal shooting of a 19-year-old El Cerrito man Monday during what appears to be a drug deal gone wrong, San Pablo police Lt. Kenneth Bays said today. Officers found the victim, Aye Alan Lee, in the 2100 block of Stanton Avenue shortly after 1:40 p.m. as they were responding to a report of a suspicious vehicle. He was slumped over in the seat, dead from a single gunshot wound to his head, police said.Investigators believe Lee called the suspects before he was killed and apparently arranged to meet them to sell them some marijuana, Bays said.On Thursday, police arrested 20-year-old Michael Williams, a resident of San Francisco and Pittsburg, on San Pablo Avenue, where he was going to a store to buy a grill for his teeth, Bays said. It was not immediately clear when police arrested the second suspect and his name was not available this afternoon.Investigators believe that Williams and the second suspect went to the Berkeley Marina after the shooting and threw the gun into the water, Bays said.The Contra Costa County Sheriff’s office’s dive team recovered a gun from the water Thursday. Police also recovered a vehicle that had recently been carjacked in Emeryville parked at the Marina.Investigators believe the suspects used the stolen vehicle when they went to shoot Lee and then ditched it at the marina when they got rid of the gun, police said.A third person was arrested in connection with the carjacking, but that person’s name was not immediately available either, Bays said. Investigators do not believe the third person was connected to Lee’s killing.Williams remained in custody today at the Martinez Detention Facility on suspicion of murder, carjacking, robbery and kidnapping. His bail has been set at $1.5 million, a county jail official said.
