Kansas father kills four children and partner, then himself

A 53-year-old Kansas father called police at 8:50 AM on Tuesday to report he had killed his entire family and was about to take his own life. When officers arrived at the home in Winfield, they heard a gunshot.

After a SWAT team broke through the door at 11 AM, they found six people dead: Ronald Williams Sr., his 44-year-old partner Kelly George, and their four children—Carol Williams, 9; Ronald Williams Jr., 7; Sarah Williams, 5; and Kelly Magee-Williams, 3.

Winfield Police Chief Robbie DeLong said his department had received reports of Williams exhibiting aggressive behavior, including confronting and yelling at people in public over the past several weeks. Officers had previously responded to the area based on reports of gunfire but had not been able to identify the source. "We have calls of just aggressive behavior, but not enough really to act on," DeLong said.

DeLong noted that Williams had displayed "some erratic behavior" but said he could not point to anything that would have indicated the outcome. "In my 20-plus years here, no, I can't remember anything remotely close to this," he said.

According to court records, Ronald Williams Sr. was a registered sex offender who pleaded guilty in 1999 to two felony counts of attempted indecent liberties with a child and one count of battery involving a 15-year-old girl.

The Kansas Bureau of Investigation said it had not determined a motive. This incident marked the second familicide in the Midwest in two weeks, following a similar incident in Michigan.
