BRADENTON, Fla. (AP) — A 79-year-old woman mistakenly backed into seven people in a parking lot with her SUV, killing three of them and injuring four.

The Florida Highway Patrol said in a news release Wednesday that Doreene Landstra of Palmetto has been ordered to appear in court next month after receiving a citation for improper backing.

The collision happened Sunday at the Sugar Creek Country Club, a mobile home community about 45 miles south of Tampa. Residents had gathered for church services inside a clubhouse building.

According to a police report, Landstra began backing her 2009 Chevrolet Tahoe SUV out of a parking space, pulled forward when she realized she needed more room to clear another parked vehicle, and then struck the seven people when she began to back up again.
