Waterloo regional police say they have charged a 26-year-old woman with second-degree murder in the death of her eight-month-old son.

Officers responded to a medical incident involving the 26-year-old woman in the area of Fairway Road South and Wilson Avenue in Kitchener around 4 p.m. Sunday.

According to police, they received information during the call that resulted in them performing a well-being check at an apartment, on Cedarwoods Crescent.

"She was being transported to hospital when investigators learned information that made us check on the wellbeing [of the child]," said Const. Andre Johnson of WRPS.

Police said an eight-month-old boy was found dead at the apartment. The boy's death is being investigated as a homicide, according to police.

"Any homicide within the community, especially one that involves a child, is definitely traumatic," said Johnson.

Darby Kent, who lives two doors down from the unit where the boy was found, said she returned home from a mini vacation and found police in her building.

"It was very much a shock to me," she said.

Kent said knowing the incident happened so close to her was nerve-racking.

"I've been thinking about moving out for a while and now I really want to move out," she said. "Just a little too close to home."

Kent said she'd spoken to the accused a couple of times, but didn't know her well.

"I probably knew her a little better than other people in the unit, but I don't know her name or anything like that," she said. "I saw her walking with her stroller here and there, but I didn't really know her."

Kent added she was devastated by the news of the boy's death.

"I was just in shock that anything like this would happen in Kitchener," she said.
