OMAHA, Neb. (AP) — A 61-year-old middle school teacher has died after his SUV crashed in northwest Omaha.

David Markley, a seventh-grade science teacher at Kiewit Middle School, died after crashing his car while crossing Blair High Road early Tuesday morning.

Rescue squad personnel from Irvington and Bennington responded to the crash. Markley was taken to a hospital, where he was pronounced dead.

Millard Public Schools spokeswoman Rebecca Kleeman says Markley had taught in the Millard district for 10 years. A letter that went to Kiewit families from Principal Marshall Smith says Markley had a heart attack while driving to school.
