FORT WAYNE, Indiana (AP) -- A man accused of killing his family told police he beat and strangled his wife and killed their three young daughters after the couple argued about household chores, according to court documents. Police found Simon Rios, 33, on the front porch of his home after getting a suicide call early Tuesday. Inside, they discovered blood in the living room and Rios' wife and their three children dead in a bedroom. Rios pleaded not guilty Wednesday to four preliminary counts of murder and two counts of moving a body. He was jailed without bond. Autopsies showed the girls -- ages 10, 4 and 20 months -- had all been strangled. Their mother, identified as Ana L. Casas, died of a blow to the head and strangulation, the coroner said. Rios told police he and his wife argued after she arrived home from work about 1:30 a.m. Tuesday, according to a probable cause affidavit. He said he hit her with a steel pipe, then strangled her with an extension cord, the affidavit states. He then strangled one of the girls with his hands and used an extension cord to kill the other girls, according to the affidavit. Neighbor Nancy Gater said Simon Rios worked at a factory but had lost his job this year. So he admitted it to police, but pleaded not guilty. Hrmm. I wouldn't have a problem frying this guy, personally.
