A 7-year-old boy was treated for burns Tuesday after his 14-year-old cousin allegedly smeared hand sanitizer on his back and lit him on fire, according to Police Chief Brian Krueger.

The 7-year-old boy’s parents brought him to Mayo Clinic Health System in Austin around 7:50 p.m. Tuesday evening. He sustained burns to his back.

The boy told his parents and hospital officials his older cousin put hand sanitizer on his back and lit it on fire.

Krueger said the boy’s extent of injury and severity of burns are unavailable at this time.

Mower County Human Services and the Austin Police Department are working with the boys’ families to get to the bottom of the matter. Austin police detectives are investigating further, Krueger said.
