(WGN-AM)-A man found dead and burned at a Southwest Side residence Friday has been identified as William Hallin, according to a Cook County medical examiner's spokesman. The death was being investigated as a possible homicide, pending the results of an autopsy, police said today.

Hallin, 67, of the 6100 block of South Kenneth Avenue, was found about 6 p.m. in the 5000 block of South Talman Avenue in the Gage Park neighborhood, police said.

Hallin was found in the basement of the building, which is an apartment house, and his death is being investigated as a possible homicide, Chicago Police News Affairs Officer Robert Perez said today. An autopsy on Hallin's body was scheduled for today.

A woman who lives next door to where the man's body was found said she saw police take three people who lived in that residence -- two men and a woman -- away from the residence in a squad car.

Police said today that the three were residents of the apartment building and they were being questioned as witnesses.

She said she did not know them, but said the apparent victim owned that residence. She said she did not know the victim's name.

"It seemed like a fire. There was a lot of smoke," the neighbor, 23-year-old Carmen Zavala, said about 9:20 p.m. "The body's still inside. They haven't taken him out."

Zavala said police told her the body was in the basement.
