FORT WAYNE, Ind. (WANE) – The deaths of three people who were pulled from a house fire in the North Highlands neighborhood are considered “suspicious,” according to Fort Wayne Police Spokesperson Sofia Rosales-Scatena. One of the deaths has been confirmed a homicide, according the the Allen County Cornoner’s Office.

Marcos Ildefonso Casares, 37, died of multiple gunshot wounds and the manner of death is homicide. He is believed to be homeless. Rosales-Scatena told WANE 15 that Casares is not from Fort Wayne. Investigators believe he is from East Chicago.

The cause and manner of death for Doak Stanley McBride, 51, and Kyle Gregory Call, 32, are pending the final autopsy report. McBride and Call are from Fort Wayne.

It is unclear at this time how the three ended up inside the home on Rosemont Drive. Investigators are looking for personal history on all three men.

A joint investigation is being conducted by the Fort Wayne Police and Fire Departments. Investigators are awaiting the results of two autopsies to determine if foul play was involved.

According to officials at the scene, a police officer was patrolling the area early Friday morning when he saw smoke coming from the North Highlands neighborhood. The officer followed it to 1840 Rosemont Drive and found smoke and flames coming out of two windows and the front door.

The officer called it in around 1:10 a.m., and fire crews responded in just four minutes. Firefighters quickly worked to put out the flames and went into the home to search for victims.

They found three people inside. Two of them were already dead.

Firefighters removed the third victim from the home and administered emergency care until medics arrived. They took the man to a hospital in critical condition where he was pronounced dead.

Four arson investigators were on scene collecting evidence and taking pictures, but they have not released an official cause at this time.

Arson investigators contacted the Fort Wayne Police Department’s homicide unit to assist with the investigation. Police officials said the investigation is still in its early stages and they did not have any additional details as of Friday morning.

The interior of the home sustained heavy fire and smoke damage. No firefighters or emergency personnel were injured while working the house fire.

The identities of the victims should be released by the Allen County Coroner’s Office at a later time.
