El Cajon, CA police have not been able to identify a suspect in the gruesome murder that took the life of Shaima Alawadi, an Iraqi mother of five who was beaten to death in her home last Wednesday. El Cajon, which is a few miles west of San Diego, has one of the nation's largest Iraqi communities. Police say Alawadi's 17-year-old daughter Fatima Al Himidi found her mother unconscious in the family's home on Wednesday after being beaten with a tire iron. Alawadi died Saturday, a short while after being taken off life support.
