Waunakee police say they have had several contacts with homicide suspect Ronald D. Jenne in 2018, including those that caused concern over possible mental health issues.

Jenne, 74, was charged with first degree intentional homicide after a woman died from gunshot wounds Friday evening in Waunakee.

"We put him in contact with mental health services on several occasions," Waunakee Police Chief Kevin Plendl said.

Waunakee police were called to an apartment complex for a report of a person who was shot at 201 Kearney Way at 5:06 p.m., according to the Waunakee Police Department.

"This incident started when Jenne came to the victim’s apartment to speak with her. She let him inside the apartment, and Jenne caused a disturbance and started using profanity prior to the shooting,” Chief Pendl said.

The victims 15 year old son and four year old grandson were in the apartment at the time the shooting occurred.

Jenne, who was a resident of the apartment complex, had retreated into his apartment after the shooting, which was directly across the hall from the victims apartment.

The Dane County Sheriff's Office Tactical Response team and a negotiator contacted Jenne via phone. Jenne surrendered without further incident, according to the Waunakee Police Department.

A .38-caliber handgun was recovered from the suspects apartment and believe to be the gun which was used.

An autopsy is scheduled for Saturday morning and the victim's name will be released Saturday evening. A press conference will be held this afternoon at the Waunakee Police Department.

The Dane County Sheriff's Office and Waunakee Police Department are still investigating.
