Carbon monoxide poisoning appears to be the cause of death for three people in Flint, including an 11-year-old boy.

According to WNEM, emergency crews were called to the scene on the 600 block of Foss Avenue after another family member in the home noticed the two adults weren't breathing. Investigators said that a poorly ventilated fireplace may be to blame. Autopsies on the victims will be performed, but could take weeks to complete.

Police identified the deceased as 43-year-old LeTroy Edwards, 37-year-old Selena Carranza and 11-year-old Jason Cobbin.
