The family of a slain 72-year-old woman on Thursday filed a $14 million lawsuit against her Baltimore apartment complex, alleging her murderer was allowed to kill because of lax security.

On June 2, Leo Cooper entered his mother Shirley Cooper?s home, located in the Temple Gardens apartments located at 2601 Madison Avenue, to find her dead as a result of multiple stab wounds. Police have made no arrests, but have closed the case after their main suspect was found dead.
