Richmond police Lt. Bisa French said Friday that 19-year-old Mercedes Williams and her brother, 16-year-old Darian Holly, died at the scene of the Thursday night shootings.
French tells the Contra Costa Times ( http://bit.ly/14CctyS) that two suspects approached the family, pulled out guns and started shooting. A car pulled up and the suspects fled into it.
Capt. Mark Gagan says Richmond police are noticing that victims and suspects in street-shootings are getting younger.
