MORRIS HEIGHTS, the Bronx (PIX11) — Two people died and two others are fighting for their lives after a fire ripped through a Bronx apartment building on Thanksgiving morning, police said.

The blaze engulfed two apartments in the building at 1730 Harrison Ave. near West Tremont Avenue in Morris Heights at around 5:25 a.m., officials said. A 20-year-old woman and a 60-year-old man died and two other women, ages 62 and 63, were taken to the hospital in critical condition, police said.

Investigators believe the four victims are family members, according to an NYPD spokeswoman. Neighbors said the man and woman who died were a father and daughter.

Authorities said the fire wasn’t deemed suspicious and may have started in a kitchen. They have not yet determined the cause of the fire.

One building resident said residents have complained about the heat and boiler. A check of Department of Building records for the address shows a complaint from November 2021 with a violation issued. There are no open violations listed now.

The FDNY said the fire was brought under control by 6:19 a.m.
