There is nothing that I can say that will heal anyone's pain, but I do want to express my sincere condolences to everyone affected by this terrible tragedy.

Cleveland police said at the time of the shooting, a group of men showed up to a party uninvited, and were asked to leave.
Moments later, investigators said shots were fired into the crowd of people, and they identified Biles-Thomas as a shooter.
DelVaunte Johnson, 19, and Toshaun Banks, 21 died at the scene. A third victim, identified as Devaughn Gibson, 23, died at a hospital. Two other people were wounded in the shooting.
Authorities in Liberty County, Georgia said Biles-Thomas was arrested at Fort Stewart, where he is a cannon crewmember assigned to 3rd Infantry Division. He joined the Army in 2014.
Biles was placed in foster care at a young age and did not grow up with Biles-Thomas, according to multiple media reports. She and her younger sister were raised by their grandparents, Nellie and Ron Biles.
Biles-Thomas is expected in court Sept. 13.
