Baltimore (WBFF) — A Baltimore County caregiver says Maryland Child Protective Services put her “in the line of fire” and didn’t tell her. Angela Studivant, for five years, worked as a Child Care Specialist at The Children’s Home in Catonsville. During that time, she says she cared for Walter Martinez, the MS-13 gang member who murdered 20-year-old Kayla Hamilton in Harford County. And the whole time, she had no idea she was caring for a killer.
