INDIANAPOLIS -- Neighbors and city leaders gathered Tuesday night to mourn two women and two children fatally shot in their home late Monday night as the neighborhood comes to grips with the brutality of those killings.

Tired of violence and fed up with the killings, community leaders and hundreds of mourners once again called for peace at a community vigil at the Great Commission Church of God.

Mayor Greg Ballard, city Police Chief Michael Spears and Sheriff Frank Anderson attended, as did people from the neighborhood and many other areas of the city.

Police on Tuesday said they had no suspects in the slayings of Gina Hunt, 24; her 23-month-old son Jordan Hunt; Andrea Yarrell, 24; and Yarrell's 4-month-old daughter Charlii Yarrell. But authorities said at least one person saw two unidentified men running from the house shortly after gunfire was heard there.

"This community needs to see unity," said pastor Art Leftridge. "This community needs to see us come together."

Tears were shed and pain was shared over the especially heinous crime, which left two slain mothers clutching their dead children.

"We will labor mightily with every ounce that that we have to make sure that this act doesn't stand and that we do not live in a community where a baby can be shot in a mother's arms," said Scott Newman, Indianapolis public safety director.

The families want justice as they fight through their grief.

"Whoever the person is -- might even be sitting in here right now -- we don't know, but … God knows. He knows everything," said Doris Hill, cousin of one of the victims.

"It shouldn't take something like this for the community to come together," said Kiyanna Sampson, another cousin of one of the victims. "We should be out on those streets every week praying."

Residents who live in and near the 3200 block of Hovey Street, where the slayings took place, said they are accustomed to drug activity and break-ins, but they're not used to anything like Monday night's slayings.

Jennifer Thomas, who lives two doors down from the house where the four were killed, was filled Tuesday with an emotion that many in the neighborhood said they shared: She was terrified.

"I'm very scared for my family and for everybody around here. I'm just praying and asking God to help us," Thomas told 6News' Rick Hightower.

Police said the women were holding the children when they were shot. People in the neighborhood were especially disturbed by the children's deaths.

"To kill two innocent babies that don't have a chance in this world, that's just sad to me," said Shomar Bullock, who lives in the area.

"When there's children involved, this becomes a very sensitive, very emotional time. And it's not just for family members -- I mean the whole entire city," said the Rev. Malachi Walker, the church's assistant pastor.

Clarissa Patton, who lives on Indianapolis' west side, said she attended because her brother and her husband were killed in 2005.

"I understand the hurt and the pain and the suffering that comes behind all of this. The very least I could do is to show my support and to be here for others who have been faced with such a tragedy," Patton said.

Angela Lamb, who lives in the neighborhood where Monday's killings happened, said she had long been worried about crime there.

"I wish something could be done. I'm scared every day. I'm scared right now," Lamb said.
