Two Boys, Dominick Wilk And Isaac Dunner, Die After Being Trapped In Car Trunk

Two young boys, ages two and four, have died in a small northern Indiana town after their mother found them trapped in the trunk of a car on Friday.

Isaac Dunner, the younger boy, died later that day, as temperatures outside were around 85 degrees. His half-brother Dominick Wilk passed away the following day at Memorial Hospital in New Carlisle, the Associated Press writes.

According to the South Bend Tribune, their mother, Jacqueline Wilk, discovered them in the trunk of the 2000 Chevy Malibu at around 3 p.m. It's unclear how long they had been in the trunk, or how they got in in the first place.

The Tribune describes the boys' grief-stricken parents:

At about 3:30 p.m., neighbor Josh Esquibel said he saw the father of one of the boys drive up the street “fairly fast” and stop in front of the home.

“He got out, and he was weak in the knees,” Esquibel said, noting that police had to “hold him up under a tree.

“He almost fainted.”

As police performed CPR on the boys at the scene, neighbors heard the mother crying and screaming.

WNDU, the area's NBC affiliate, reports that Rev. Donald Bayne Jr. of the New Carlisle Wesleyan Church issued a statement on behalf of the family. "We simply have no way to express the sorrow at the loss of Dominick and Isaac," they said, according to Bayne.

The community is doing what it can to help the family, according to a separate WNDU report. The New Prairie Little League team, where the 4-year-old Wilk played baseball, was scheduled to have a team fundraiser this week at a neighborhood pizza restaurant. But instead of the proceeds going to the team, they'll now be donated to the Wilk family.

An autopsy is expected on Monday to reveal more details about the circumstances of the boys' deaths.
