COLORADO SPRINGS, C0 — The mother of a 17-year-old bride chased the bride's father through the house at the wedding reception, fired a rifle at him and accidentally killed her new son-in-law, police said yesterday.

Simmons had been married at the Harris home about six hours.

Marvin Simmons, 24, an Army private first class at nearby Fort Carson, was hit in the head by a bullet from the .22-caliber semi-automatic rifle.

Shirley May Harris, 31, the bride's mother, was booked for investigation of homicide, authorities said.

Simmons had been married at the Harris home about six hours before the shooting. Friends said that Simmons and his bride, Sherry Harris Simmons, 17, were childhood sweethearts.

El Paso County Deputy District Attorney Bill Aspinwall said Mrs. Harris and her husband, Lonnie, had been arguing in a bedroom during the reception. The subject of the argument was not disclosed.
