A man accused of killing his former partner was back in court Thursday afternoon. 31 year old Sebastian Mabb, 31, allegedly killed Brianna Craig, the mother of his child, inside her home on Vanderbilt Terrace in Saratoga during a domestic incident on Feb. 6. Prosecutors told Judge Jim Murphy that they are ready to proceed to trial, and they’re still waiting for lab and DNA reports and the results of a search of Mabb’s social media.
