Cleveland's deadliest house fire claimed the lives of eight children and a mother on May 21.

NewsChannel5 reported that the reward for information in this arson fire was just increased to $25,000.

Tom Ganley, of the Ganley Auto Group, came to NewsChannel5 Wednesday to announce his intention to up the reward from $20,000 to $25,000, the biggest crime reward in northeast Ohio's history.

NewsChannel5's Joe Pagonakis reported that Miles Cockfield, 13, was killed by toxic smoke produced by a fire set by an arsonist at the home. His mother shares her continued pain a half year later.

"I can't say even if you lost a child you would know the pain. There's no words for it," Crystal Ingram said.

A group of children who stayed together as a family, and tragically died together. The 33-year-old mother, Madeia Carter, who took the children into her home, was killed. Pagonakis said that it was a birthday party sleepover that turned into murder at the hands of an arsonist.

Carter's sister also lost her 13-year-old son, Earnest Tate Jr., in the fire.

"It's hard to lose a child, a sister. It's extremely hard," Shelfie Carter said.

Children, like 12-year-old Shauntavia Mitchell, 7-year-old Fakih Jones, 14-year-old Antwon Jackson, 15-year-old Devonte Carter, 12-year-old Maleeya Williams and her brother, 14-year-old Moses William Jr. and Miles had their whole lives ahead of them.

"I want him here, I want him here. You can see the tears our kids are crying. We need someone who will help us out. We need some help," Ingram said.

NewsChannel 5 is holding a phone bank in partnership with Crime Stoppers to get any information about the fire.
