A pregnant woman in her mid-30’s and a 7-year-old boy lost their lives in a house fire that sent  seven other people to a hospital.

It happened on Tuesday, Dec. 4, in St. Joseph County, Michigan.

WWMT is reporting that 11 people, including seven children, lived at the home on South Washington Street in White Pigeon where the fire broke out around 3:30 a.m.

A 15-year-old boy made the call to dispatch, according to 95.3 MNC’s reporting partners at ABC 57.

A smoke alarm was going off in the home when crews arrived.

White Pigeon Fire Chief Troy Andrews says crews found several residents outside and were told two were still on the home’s second floor. He said firefighters tried to get inside but were pushed back by intense flames.

Seven people were sent to the hospital suffering from smoke inhalation, and two others made it out of the house safely.

Andrews says a dog was found dead in the basement and another was found alive.

Chicago Road/US-12 was shut down between St. Joseph and Washington Streets in White Pigeon to allow for crews to work the scene.

Officials believe the fire may have been the result of an electrical problem.
