Sheriff: Parents, 3 Kids Found Dead in North Texas A grandfather discovered the lifeless bodies of his three grandchildren, his son and daughter-in-law at their home in North Texas. Navarro County Sheriff Elmer Tanner said Monday that the victims were shot and the deaths are being investigated as murder-suicide. Tanner says the man discovered the bodies of Israel Alvarez and Guadalupe Ronquillo-Ovalle with their children on Sunday night. A rifle was recovered from the home near Rice, 40 miles southeast of Dallas. The children were aged 10, 8 and 4, and their parents were both 33-years-old. Records show Alvarez was arrested Sept. 11 on a misdemeanor family violence charge. He was accused of shoving his wife and taking her phone because he thought she talked to another man. Alvarez pleaded no contest, paid a $367 fine and was freed.
