An Arizona man suspected of killing his wife and two stepchildren before they left to visit family in Cambridge. is out of jail. Fifty four year old David Anthony was arrested Saturday for investigation of three counts of first degree murder. He was released from jail late this morning because porsecutors say they lack adquate evidence to bring formal charges. The Maricopa County Sheriff says his detectives will be keeping a close watch on Anthony, though, as they continue their investigation. Anthony's wife 53 year Donna Anthony, and her 12 year old son and 14 year old daughter haven't been seen since July 7th.
