MINNETONKA (AP) — The children of a Minnetonka couple killed in a house fire have identified their parents as the two victims.

The couple killed was 78-year-old Brian Humphrey and his wife, 76-year-old Sandra Humphrey. Authorities say the fire that started about 10:30 p.m. Friday appeared to be accidental.

A neighbor says she spotted flames in the Humphreys' front window and that they quickly engulfed the house. Lorraine Besonen says it took firefighters several hours to extinguish the flames.

The Humphreys' children say their parents dedicated their lives to their community and faith. Sandra Humphrey was a retired clinical psychologist and children's book author. Brian Humphrey was retired from a job at SuperAmerica and was active in charitable efforts to fight hunger.
