OAKDALE, Minn. - A 6-year-old girl came home from school and discovered her parents and live-in baby sitter dead in what police said was a double murder-suicide in the Twin Cities suburb of Oakdale.

Teenage neighbor Brady Hartman told the Star Tribune that the child came home from school Thursday and found the three dead. He said the girl ran out of her house sobbing and screaming, "Mommy, daddy dead! Mommy, daddy dead!"

Hartman's mother consoled the girl and called 911.

Oakdale police said Friday the deaths of two women and one man are being investigated as a double murder-suicide and they are not actively seeking suspects. Oakdale police Officer Michelle Stark said the man's death was ruled a suicide.

A preliminary investigation by the Ramsey County medical examiner's office determined each of the three died of a gunshot wound to the head, police said. Investigators recovered a handgun and spent ammunition at the scene.

Police identified the three people found in the two-story home as Jaime Velasquez, 32; Cintia Guadalupe Ornelas Bustos, 28; and their baby sitter, Angela Uscanga Gonzalez, 43. Velasquez and Bustos had three children, they said.

Stark would not confirm reports that the young girl discovered the bodies.

It was not clear whether other children were home at the time of the killings. The Star Tribune reported that the girl and her brothers, ages 3 and 8, were staying with relatives.

Relatives said the couple owned All Seasons Siding and Roofing.
