MADISON, Wis. (WMTV/Gray News) – The Wisconsin man accused of intentionally driving into a family and killing the mother as an act of revenge has died in jail, sources say.
Two trusted sources of WMTV confirmed Jeffrey Endres, 49, was found unresponsive and died Tuesday.
Online records show that Endres is no longer listed as a resident of the Dane County Jail.
The Dane County Sheriff’s Office confirmed an inmate died but did not confirm an identity. The sheriff’s office said first responders attempted to save his life, and he was pronounced dead at the jail.
The Madison Police Department said detectives processed the scene at the jail Tuesday, collected evidence and spoke with jail staff.
An autopsy is scheduled for Thursday.
Endres was charged Monday with first-degree intentional homicide, two counts of attempted first-degree intentional homicide and mistreatment of animals causing death.
Prosecutors said he intentionally hit a family with his vehicle while they were out on a walk on April 28, killing the mother and the family dog.
A criminal complaint released Monday alleges Endres sped up and crashed into the family in Cottage Grove, a suburb of Madison.
According to the criminal complaint, Hansen’s husband told police that allegations of a sensitive crime between his child and Endres’ child were brought forward in late March.
A Cottage Grove Police Department school resource officer investigated the alleged incident in March, and a juvenile court proceeding was held on March 28.
The complaint stated that Endres filed an open records request on April 23 for police reports related to the alleged incident between the two children.
A redacted set of police reports was forwarded to Endres less than three hours before the deadly crash on April 28, the document confirmed.
