Jashon Williams, 17 mos, MSG 11/13/09 Oakland, CA (Mom slain)(BODY FOUND)

A parolee from Oakland was charged today with two counts of murder and special circumstances for allegedly killing his girlfriend and her 17-month-old son and dumping them along the Berkeley shoreline.

Authorities, confirming for the first time that the body of a child found in the bay Sunday was that of Zoelina Williams' son, theorize that Curtis Martin III murdered the boy first. Then he killed Williams to keep her from revealing what he had done, police believe.

Martin is accused of fatally beating Zoelina Williams before dragging her body from his van to the shoreline at Berkeley's Aquatic Park early Friday. While wearing rubber gloves and protective booties over his shoes, Martin was surprised by Berkeley police Officer Darren Kacalek, according to sources and court documents.

Martin explained that "he had just been kicked out of the Berkeley Marina," on the other side of Interstate 80, authorities said in a court affidavit. Jashon's body was later found floating near the marina.

Kacalek checked Martin's identification, warned him the park was closed and sent him on his way, police said. But as Martin drove away in his van, the tires ran over what the officer thought was a stick. It turned out to be a rifle, and Kacalek then saw drag marks that led from the van to Williams' body, sources said.
