A man pleaded guilty Friday to four counts of murder and other charges in the 2008 killings of two women and two children at a Hovey Street home in a plea deal with prosecutors that allows him to avoid the death penalty.The Marion County Prosecutor's Office said Thursday that Prosecutor Carl Brizzi was working out a plea deal with Ronald Davis, 33.At a hearing Friday morning, Davis initially didn't admit that he was a triggerman, 6News' Derrik Thomas reported, but said he was involved in a robbery at the home in the 3200 block of Hovey Street in which Andrea Yarrell, 24, Charlii Yarrell, 5 months, Gina Hunt, 24, and Jordan Hunt, 23 months, were slain."If I didn't kill nobody, I'm not going to say I killed somebody," Davis said in court. "I was at the wrong place at the wrong time."After a recess, attorneys convinced him that in the eyes of the law, he was still guilty of felony murder."He didn't kill them, and today he was allowed to plead guilty to those things that he did do," said Monica Foster, Davis' attorney. "He was involved in a robbery where people were killed.""Someone shot them. Who that is, maybe nobody knows," said Jerry Hunt, father of one of the victims. "Between he and Jasper Frazier, somebody shot those children in the face. So, until we find that information out, God is the only one who knows."Police said Davis and his four co-defendants -- Tommy Warren, 27; Donte Hobson, 32; Jasper Frazier, 39; and Zarumin Coleman, 24 -- believed there were drugs in the house, but prosecutors said in the aftermath of the slayings that they had found no evidence that drugs were being sold there.Hunt's mother, Elizabeth Duncan, said she didn't want Davis to get the death penalty, but she has no doubt he is responsible."I'm going to pray for Ronald Davis, because I know who did it -- Ronald Davis," Duncan said."He is legally responsible. He is morally responsible," said Marion County Prosecutor Carl Brizzi. "He faces a very slow death of dying in prison."Davis will be sentenced Oct. 14. He could receive between 45 and 280 years in jail.Frazier, Warren, Hobson and Coleman were charged with conspiracy to commit robbery.
