SAN ANTONIO (AP) — A woman who police say shot her two kids and then killed herself during a standoff in a state welfare office has been identified as a former Ohio resident who moved to Texas this summer.Authorities on Tuesday identified the mother as Rachelle Grimmer. Laredo police investigator Joe Baeza said the 38-year-old formerly lived in Zanesville, Ohio, about 30 miles outside Columbus.Grimmer's 12-year-old daughter, Ramie, and 10-year-old son, Timothy, remained in critical condition Tuesday at a San Antonio hospital.State officials say Grimmer applied for food stamps in July but was denied because she didn't turn in enough information.Authorities said Grimmer told negotiators about a litany of complaints against state and federal government agencies during the standoff at a Texas Department of Health and Human Services building.
