A father separated from his family and struggling financially burst in on his estranged family on Christmas morning and massacred them, NBC DFW reported. The man, Aziz "Bob" Yasdanpanah, is believed to have killed six family members -- including his estranged wife and two children -- and them himself. He was wearing a Santa Claus suit, police said, and unwrapped gifts still lay around the bodies when police found them. "Bob loved his kids. And I can't even fathom that that's what happened," said Terri Baum, a neighbor. Yasdanpanah's home was foreclosed last year, and he separated from his wife in the spring. Police had not officially named Yasdanpanah as a suspect, but investigators are focusing on him, NBC DFW reported.
