Uber is helping investigators look into an account that sent a driver to the Ohio home where an 81-year-old man allegedly shot the woman to death because he erroneously believed she was part of a scam that targeted him, the ride-hailing company said Wednesday.

The March 25 shooting death of Loletha Hall is “a horrific tragedy,” and that account has since been banned, an Uber spokesperson wrote in an emailed statement. “Our hearts continue to be with Loletha’s loved ones as they grieve.”

William J. Brock was indicted Monday on charges of murder, felonious assault and kidnapping for Hall’s death. Messages seeking comment were left Wednesday for him and for his lawyer, Paul Kavanagh of Springfield, Ohio.

The grand jury also said that a gun seized from Brock’s home, a .22-caliber revolver, is subject to forfeiture. Brock has pleaded not guilty.
