Police: Man sought in Iowa slayings case said he killed 3

BONDURANT (AP) — A man sought as a material witness in the slayings of his parents and sister in their suburban Des Moines home surrendered in Missouri on Friday and told an officer there that he had killed three people, authorities said.
The Polk County Sheriff’s Office said in a news release that 20-year-old Chase Nicholson surrendered to police in Neosho, Missouri. Iowa authorities had sought him on a material witness warrant. Iowa online court records don’t show that he’s been charged with a crime in this case.
But a written statement from the Neosho Police Department said Nicholson told an officer Friday morning that he had killed three people the night before. The department said the officer came in contact with Nicholson after police were called by employees at a local Wal-Mart, who said a man was there asking for help.
Polk County detectives were traveling to Missouri to talk to Nicholson and Missouri investigators, the Sheriff’s Office said.
Deputies sent to the residence in Bondurant, Iowa, to check on the welfare of the people living there found the bodies around 9:30 p.m. Thursday. The three were identified as Mark Nicholson, 58, his wife, Charla Nicholson, 56, and their daughter, Tawni Nicholson, 24.
Authorities believe Chase Nicholson lived with them at the home in Bondurant, which sits on the northeast corner of Des Moines.
Neosho, Missouri, is about 340 miles southwest of Bondurant.
The Sheriff’s Office declined to say when and how the three people were killed and whether a weapon had been recovered.
Iowa online court records show that Chase Nicholson was arrested in May 2014, accused of throwing a fireplace utensil at his father, cutting the man’s face.
The case was dismissed in December 2015. According to the records, Chase Nicholson had completed a class on curbing assaultive behavior and his father requested the dismissal.
