SAC CITY, Iowa (AP) — Authorities have released the name of a crop-dusting pilot who was killed when his plane crashed in western Iowa.

The plane wreckage was discovered around 9:45 a.m. Friday by a crew responding to a power outage about 3½ miles south of Sac City. The Sac County Sheriff’s Office said Monday that a preliminary investigation shows the plane clipped the static lines on high-voltage lines and came down in a cornfield.

The Sheriff’s Office says in a news release that the pilot has been identified as 44-year-old Mark Watson, who lived in Burlington.

An autopsy has been ordered.
