OAKLAND -- Murder charges have been filed against a man in a fatal 2010 shooting of a former friend and business associate in East Oakland, authorities said Monday.

Michael R. Smith Jr., 36, is accused of the July 30, 2010, killing of Montago Bey Joshua, 45, of Hayward, a well-known Oakland tattoo artist.

Police said Smith and Joshua formerly worked together as tattoo artists and had a falling out over the business and other matters.

Joshua was shot outside a barber shop in the 9900 block of MacArthur Boulevard by a gunman who fled in a car. Police said they got tips at the time that Smith was the gunman but did not have enough evidence to arrest or charge him.

Officer Mike Cardoza said that after the shooting, Smith fled to Oregon, but he returned to the area several months ago.

Smith was arrested on suspicion of domestic violence in January but was released when no charges were filed.

Cardoza said a relative of Joshua's heard Smith was back in town and had been arrested, and another person also contacted police to let them know he was in the area.

Police were then able to develop enough evidence that allowed them to obtain a probable cause warrant for Smith's arrest. He was arrested March 12 in Oakland and admitted his involvement in the killing, Cardoza said. Smith is being held at Santa Rita Jail on $3 million bail and is scheduled to enter a plea Tuesday.
