A mother and her teenage daughter in Missouri were shot dead inside their own home by a neighbor who came over to complain about a "dispute," police said.
Robert Winkelman, 73, walked down the street to his neighbor's House Springs, Missouri, home and confronted 38-year-old Jessica Lashly about what was going on at her house on July 25, the Jefferson County Sheriff's Office said. When Lashly responded, Winkelman pulled out a gun and shot her in the head.

When the victim's 17-year-old daughter, Jersey Greer, tried to help her mother, Winkelman shot her in the head as well, the sheriff's office said. A third person was chased by Winkelman as he was armed with a gun, but wasn't shot. Both Lashly and Greer died days later at a local hospital.
When deputies arrived at Winkelman's home and moved to confront him, he turned the gun on himself.
He died at a local hospital on Aug. 2, according to investigators, who said he would have been charged with two counts of first-degree murder and two counts of armed criminal action.
