BERKELEY (BCN)--A 6-year-old boy has died from injuries he suffered in a car crash  in Berkeley 11 days ago that also killed his mother and injured her  boyfriend.

     

Xavier Chevez died at about 6:30 p.m. Friday at Children's  Hospital Oakland, Berkeley police spokeswoman Sgt. Mary Kusmiss said Tuesday.

     

The boy was injured at about 1:10 a.m. on May 18 when the Cadillac  he was riding in crashed into a roundabout and a tree near Allston Way and  California Street.

     

Xavier's mother, 22-year-old Milanca Alicia Lopez, was killed in  the crash. Lopez had been a student at the University of California at  Berkeley, where she studied social welfare.

     

The driver, 24-year-old Jose Lumbreras, was taken to a hospital  after the accident with what police described as serious injuries.

     

The Alameda County District Attorney's Office last week charged  Lumbreras with gross vehicular manslaughter while intoxicated for Lopez's  death, and drunken driving causing injury for the wounds to Xavier, who  became comatose after the crash and suffered paralysis.

     

Kusmiss said the second charge might be amended as a result of  Xavier's death, but district attorney's spokeswoman Teresa Drenick said a  decision on amending the charge won't be made until Wednesday.
