DES MOINES, Iowa — Des Moines Police are investigating the death of a two-year-old boy that happened last week.

Sgt. Paul Parizek with the Des Moines Police Department says the child was unresponsive at a Des Moines residence and brought to Mercy Medical Center in the early morning hours of May 24th. The child died later that day.

Parizek says the department has not identified  anything criminal about the child’s death, but police must complete due diligence in their investigation.

“It’s part of our commitment to the community that we are going to make sure that we look into things that are curious and are rare and don’t naturally occur all the time,” Parizek said. “It’s our job to find answers so we can understand why things happen, and that’s what we are going to do here.”

The name of the child was not released by police, but the child’s mother confirmed to Channel 13 that her son Calvin Risius is the focus of a death investigation by police.

The mother tells us her son died from lack of oxygen to the brain following a seizure.

An autopsy and other forensic investigations will be conducted in the case.

A memorial motorcycle ride is planned for Sunday, June 24 starting at 12:00 p.m. at Sudsuckers, 1511 Army Post Road. A fundraising benefit with dinner will be held by the family at Sudsuckers following the ride.
