A manhunt is underway after the bodies of a southeast Kansas mother and her three young children were discovered Tuesday.

The victims are 29-year-old Cami Umbarger, of Parsons, and her three children, the Kansas Attorney General's Office said in a news release. Authorities did not say how they were killed or provide other details about their deaths.

The search for the 22-year-old suspect moved to Independence, where he was last seen at about 12:45 p.m. Tuesday, the Montgomery County Sheriff's Office said in a statement.

The suspect is considered armed and dangerous, and authorities warned people not to approach him. He has not been charged.

Umbarger is a licensed practical nurse who worked at the Good Samaritan Society, a nursing home in Parsons. The nursing home confirmed her employment but declined comment.

The Parsons Sun reported that police received a call Monday from concerned co-workers and family members after Umbarger didn't show up for work. Umbarger's children, an 8-year-old girl, a 5-year-old boy and a 4-year-old girl, were also reported missing.

A candlelight vigil for Umbarger and her children is planned for 7 p.m. Wednesday in Parsons.

Parsons police, the Kansas Bureau of Investigation and other law enforcement agencies are investigating.

Parsons has about 10,500 residents and is about 125 miles southeast of Wichita in Labette County.
