INDIANAPOLIS -- Police are looking for two unidentified men seen running from a home where two women and two children were fatally shot Monday night, and Sheriff Frank Anderson on Tuesday said Indianapolis police won't rest until they arrest whoever killed the four.

"I can only say there's a special place in hell for you, and we're going to see that you get there," Anderson said, referring to the gunman or gunmen.

Officers responding to a report of shots fired found three people dead and a 4-month-old girl wounded in a home in the 3200 block of Hovey Street at about 10:45 p.m. Monday, police said. The baby later died at Methodist Hospital.

Police identified the victims as Gina Hunt, 24; her son Jordan Hunt, 23 months; Andrea Yarrell, 24; and Yarrell's daughter Charlii Yarrell, 4 months. Police said all four died of multiple gunshot wounds and the children were being held in the arms of their mothers during the shooting, 6News' Jack Rinehart reported.

"I can't imagine what kind of evil it takes to shoot two women and the innocent children in their arms," Indianapolis Police Chief Michael Spears said at a Tuesday news conference.

Authorities said they received a report of two men running north on Hovey Street just before police arrived. Police did not have a description of the men, and they said at 4:30 p.m. Tuesday that they hadn't identified any suspects.

Two handguns were found within a block of the home and marijuana, a scale, a safe and at least three weapons were found in the house, where all four victims lived, police said.

"She just wanted to be on her own and she got mixed up in the wrong crowd," said Jerry Hunt, Gina's father. "It cost her and her girlfriend and my grandson and her baby and her friend's baby their life."

At a news conference late Tuesday morning, Anderson had strong words for those responsible for the slaying and pledged the full force of law enforcement in solving the crime.

"We've got a team and we're going to find you. We're going to put you in the dog cage that you belong," said Anderson, who as sheriff oversees the Indianapolis Metropolitan Police Department.

Police were initially called to a vacant home nearby on a robbery report. Minutes later, they received a call reporting that someone had been shot in the Hovey Street home, 6News' Julie Pursley reported. Officers then discovered the victims.

Chaplains were brought in to talk to grief-stricken family members and friends.

"This is just ... inexplicable violence that rocks our city to the core," Spears told reporters. "I assure you we are doing everything within our power and our authority to bring a quick resolution to the matter and bring those responsible for this into custody."

Police had been called to the home at least three times within the past four months, including at least once for a robbery in September, Indianapolis police Sgt. Matt Mount said.

Gina Hunt told police in September that two armed men broke into residence and threatened to kill her and her son if she couldn't provide the location of a man whose name she said she didn't recognize.

No injuries were reported in that incident. Police said they didn't know whether the September break-in was linked to Monday's slayings.

"There's just a number of factors that have to be looked at," Mount said. "Because of the things that were found at the scene they are going to look at every possible motive."

Residents gathered at the nearby Great Commission Church of God after they heard of the shootings.

"There was a family cousin who showed up on the scene and it was very emotional," said the church's assistant pastor Malachai Walker.

He said the neighborhood has crimes such as burglaries and those connected with drugs.

"But as for homicides -- it's a shock," he said.

When new Indianapolis Mayor Greg Ballard was campaigning last year, he said crimefighting would be a focus of his administration. On Tuesday, he said the city still needs to do more to fight crime and urged residents to "maintain their sense of outrage."

"It must be channeled appropriately, but we can't forget that these things (have happened). I want citizens to not forget this stuff," Ballard said.

Police said they would like to talk to the two anonymous callers who alerted them to the shootings.
