A mother and her six-year-old son were both killed in what appears to have been a DUI accident which occurred May 18 near California Street and Allston Way near downtown Berkeley. Milanca Alicia Lopez, a UC Berkeley student in social welfare, died at the scene, while her young son, Xavier Chevez, clung to life for two weeks at Oakland Children's Hospital. He died Friday morning.

Lopez's boyfriend, Jose Lumbreras, 24, of Berkeley, has been booked on charges of gross vehicular manslaughter while intoxicated, and he registered a blood-alcohol level of more than twice the legal limit. He crashed his Cadillac, with Lopez and her son in it, into a treet at around 1:15 a.m. on May 18 and was arrested on the scene. Investigators believe he was going about 64 miles per hour when the crash occurred.
