NEW YORK (CBSNewYork) — Police are investigating after three people were found dead in an early morning fire at an apartment in Queens with stab wounds.

The fire broke out around 4:50 a.m. Tuesday in a sixth floor apartment of a building on Roosevelt Avenue in Flushing.

It was brought under control just before 5:30 a.m. Minutes after putting out the blaze, firefighters found the bodies of two males and one female inside the apartment, police said.

Sources said it appeared more than one of the victims had their throats slashed and that the fire was set to cover up the crime, CBS 2’s Don Champion reported.
