The uncle accused of executing six members of his family faced a judge Monday in Texas. Ronald Haskell, 39, was clean-shaven and wearing a suit as his murder trial got underway in Houston. Prosecutors say in July 2014, Haskell wanted revenge for his recent divorce. He allegedly stole a gun and went to the home of his ex-wife's sister. Katie Stay was first to die, trying to protect her children, according to the prosecutor. Her 15-year-old daughter, Cassidy, played dead until her uncle left. #InsideEdition
