TOWN OF LYNDON, Wis. -- A 77-year-old Wisconsin man killed in a crash involving a police car was on his way to a memorial for his granddaughter, who died by suicide over the weekend, family members told WITI.

A preliminary investigation revealed the crash happened shortly after 3 p.m. Monday. It found Dennis Teetzen was traveling south and turned east in front of the Plymouth squad car.

Deenice and Chris Warner, Teetzen's daughter and son-in-law, said Teetzen was on his way to a vigil for Nichole Warner, the couple's daughter and Teetzen's granddaughter.

"I'm going to try to find peace with both losing my father and my daughter at the same time," Deenice Warner said.

"Nichole was his world, and maybe when he went there, he was so upset, he didn't even see the car coming," Chris Warner said. "I don't know."

They opted to speak out Tuesday with hope their message would prevent a similar outcome for someone else.

"We feel it would just be a way to honor both of them, for the life that we were able to share with them," Deenice Warner said.

"If you have a child that is sick and not feeling well, do everything in your power to get them help, because the end result, they can never change their mind from that."

Deenice Warner said her daughter had been receiving treatment for depression for years, but the mental illness ultimately took over, forever changing many lives.

"If our story could save one child, it would be amazing," Deenice Warner said.

Plymouth police officer Lindsay Baumhardt, 35, was on duty and was in the squad car involved in the crash with Teetzen.

Officials said Baumhardt was not driving in emergency mode and not responding to a call.

Baumhardt suffered injuries not believed to be life-threatening. Officials said Baumhardt is the school liaison officer for the department.

Officials said Teetzen failed to yield from or failed to stop for the stop sign. His vehicle crossed into the path of the Plymouth squad, resulting in the collision.
