Authorities say a suburban Kansas City man opened fire during a weekend family gathering, killing his newlywed mother, her husband and the gunman's ex-wife, before turning the gun on himself.

Platte County Sheriff Mark Owen has identified the man who opened fire Sunday at the home in Parkville, Missouri, as 50-year-old Douglas Pauling.

The Kansas City Star reports that Pauling's 14-year-old daughter escaped the shooting unhurt and called 911.

Killed in the shooting was: Pauling's mother, 73-year-old Sharmalee Pauling; her new husband, 66-year-old Carl Deruyscher; and the teen's mother, 49-year-old Margaret "Maggie" Girard.

Pauling and Deruyscher's page on the wedding planning website The Knot says they married last month in Leavenworth, Kansas.

Parkville lies about 10 (16 kilometers) miles northwest of Kansas City.
