New York, NY —

A 30-year-old child protective caseworker was shot-and-killed in front of her two young daughters yesterday morning in the Bronx. Police say they're reviewing her past cases, but so far have no leads.

According to the Administration for Children's Services, Lakesha Scriven was hired in 2005 and was promoted to a supervisory position in September 2007. ACS says typically a supervisor has a small workload of complex cases and is mostly responsible for overseeing others.

Scriven was a member of Local 371. A union spokeswoman says fellow caseworkers have described her as a good person and a good worker, and that they're shaken up over the killing.
