OAKLAND -- An Alameda County jury on Tuesday convicted an Alameda man of murder in connection with the fatal shooting of an Oakland marijuana grower who was set up to be robbed in an Alameda apartment complex in 2011.

The jury deliberated for about one day before it found 25-year-old Christopher Donaldson guilty of first-degree murder the April 20, 2011 shooting of 32-year-old William Adrian Falcon Sapp, and of second-degree robbery for the armed robbery of another marijuana grower in Berkeley in February 2011.

Prosecutor Patrick Moriarty told jurors that Donaldson set up both victims to be robbed after answering their Craigslist ads offering marijuana for sale. Both times, Donaldson sent two other men that served as the fake buyer and the robber, Moriarty said.

Sapp fought back his alleged robber Charles Kimbrough, and then was shot and killed by the fake buyer Richard Ezell. Ezell, 25, of Mendocino County, pleaded guilty to second-degree murder in exchange for a prison sentence of 15 years to life. The criminal case against Kimbrough, 32, of Hercules, is still pending.

Defense attorney Mario Andrews had argued for an acquittal in the case. He told jurors that Donaldson did not participate in the Berkeley robbery, and was looking to buy marijuana from Sapp, not have him be robbed.

Donaldson faces at least 26 years to life in prison at his sentencing before Judge Jon Rolefson on Aug. 15.
