KANSAS CITY, Kan. (AP) — A woman says her husband was fatally shot in Kansas City, Kansas, while meeting someone he met through the mobile sales app Letgo about purchasing an iPhone 7.

The Kansas City Star reports that 45-year-old Oune Somsanith, of Lee’s Summit, Missouri, was shot Sunday afternoon. The father of five died at a hospital.

His wife, Kelly Somsanith-Hawley, said her husband loved to make money by finding deals online, but was careful. She said that whenever he met someone about purchasing a phone, he always insisted on going to a store to check to see if the phone had been reported stolen before negotiating a final price.

Letgo described what happened as an “unimaginable tragedy” in a statement and said it’s working with law enforcement. Police haven’t released any details.
