Jeremiah W. Johnson will make his first appearance at 9 a.m. today, County Attorney Todd Thompson said.

Johnson was arrested early Sunday in Tonganoxie following an altercation.

The incident occurred about 3:30 a.m. Sunday, Tonganoxie police Chief Jeff Brandau said.

Johnson’s cousin was watching the his 6-year-old and 4-year-old at her apartment. About 1 a.m. Sunday, Johnson called her, saying he needed a ride from a friend’s house because he had been drinking, reports said. The cousin took the children with her to pick up Johnson and they returned to her apartment.

Once at the apartment, the suspect said he wanted to take the children home, but his cousin wanted him to stay at the apartment. The suspect was persistent, and his cousin eventually called a female friend for help, reports said. The female friend arrived and went into the apartment while her boyfriend stayed in their vehicle.

A verbal argument broke out and the suspect took his children from the apartment, reports said.

Outside, the suspect and the friend’s boyfriend started arguing. During that argument, Johnson pointed a gun at the friend’s boyfriend.

Police arrived and arrested Johnson on charges of aggravated assault, aggravated child endangerment and disorderly conduct.

The suspect had two handguns and valid conceal and carry permits for both, Brandau said.

Leavenworth County Sheriff’s officers assisted Tonganoxie police with the incident.
