Lilly Blunt, 33, her 3-year-old daughter Lianna and 7-month old son Richard were found dead inside their Paradise Hills home on Sunday. Autopsies were pending to determine the causes of the deaths. Found in the same room was 55-year-old Clarence Blunt, Lilly Blunt's estranged husband and father to the two children. He is being treated at a local hospital after he attempted to take his own life, according to San Diego Police homicide Lt. Ernie Herbert.A police statement said the victims and the suspect were from one family, but did not specify the relationships. However, one broadcast report cited a neighbor as saying the adults were married and were possibly involved in divorce proceedings."I was surprised," said neighbor Antonio Mendoza. "I thought they were a very good family. I never heard them shouting at each other or anything like that. I never knew that they had problems. " 10News uncovered court documents that said Clarence Blunt confessed to a murder in 1974 and was in prison until 1990. 10News also learned that on July 17, Clarence Blunt went to Vibra Hospital in Hillcrest, where his wife was a nurse. He showed her supervisor two bags filled with medical supplies that he claimed she had stolen. The items included scissors, batteries and vitamins. In a declaration filed by Clarence Blunt's attorney, Lilly Blunt's former supervisor from Vibra Hospital claimed Clarence Blunt thought she was cheating on him. The documents stated, "He explained that he had learned that Ms. Blunt was having an affair with someone at the hospital and that he didn't know why he deserved that." Lilly Blunt stated she was fired. A friend of Lilly's said she was never able to find out if his claims of the stolen supplies were true or if he was setting her up. 10News called Lilly Blunt's supervisor, who did not want to speak on camera. Phone calls to Vibra Hospital's administration were not returned. On July 30, Lilly Blunt filed for a restraining order. In the documents, she detailed how she had been living in a domestic violence shelter with her 7-month-old son. She said her husband "repeatedly told me in the past that he will not allow me to divorce him When I told him on July 15 that I want to end our marriage, he told me, 'I want to hurt you right now. If you want a divorce, it will be ugly. It will be war between me and you.'" She also said that the "respondent pushes me, threatens to push me or hurt me whenever I do not do what he says or when I 'disobey' him I am terrified by this behavior." Clarence Blunt responded the next day, where he said: "There is no need for a restraining order in this case. I have never touched my wife in a harmful manner, nor have I ever threatened her with violence." Court documents reveal the two had a court appearance date of Aug. 3 to discuss the restraining order in front of a judge, but neither party showed up. The case was dismissed and no longer in effect because they did not show up. Police said authorities received a call at 5:50 p.m. Sunday from a family relative, saying attempts to contact anyone at the home in the southeastern part of San Diego near National City had been unsuccessful. Officers from the Southeastern Division responded to the location in the 2400 block of Luther Street.Herbert said officers discovered a man inside the home in need of medical attention, and they also found the woman and two children dead inside the living room.The investigation led officers to determine that the victims had been murdered, Herbert said, who added that officers had no evidence of anyone else involved in the case.The crime motive has not yet been determined, police said.Anyone with information about the case was asked to call homicide investigators at (619) 531-2293 or Crime Stoppers at (888) 580-8477.
