According to police, Donis'Morales told them both the vehicle fire and the shooting came as a total surprise to him as none of this was type reprisal was talked about or discussed prior to their arrival at the Rodriguez home.Donis'Morales story and the recovery of the alleged murder weapon prompted police to secure a murder warrant.Donis'Morales has been released without charges.Police say when Morales'Rivas surrendered to police he refused to admit to the shooting and only said he wanted an attorney.Melvin Morales'Rivas has been booked into the Liberty County jail and is now charged with murder.
