JACKSONVILLE — A maintenance man discovered the bodies of a woman and four children ages 4-10 in a Jacksonville duplex early Thursday after a neighbor reported smelling smoke, authorities said.

Police identified the victims as Marilyn Beavers, 31; Dequan Singleton, 10; Sydni Singleton, 9, Haylee Beavers, 8 and Emily Beavers, 4.

Authorities did not immediately determine the cause of death and the bodies were sent to the state Crime Lab for autopsy, Jacksonville Police Department spokeswoman April Kiser said.

“The investigation has not been completed, nor have we received a coroner’s report,” Kiser said.

Police Capt. Kenny Boyd said the Jacksonville Fire Department initially responded at 5:50 a.m. to a report of a smell of smoke in an apartment next door to where the victims were found.

Firefighters saw smoke from a fire across the highway but did not detect fire or smoke in the apartment they checked or around the duplex, so they left, Boyd said. He said the police department received a call at 7:30 a.m. that bodies had been found by a maintenance man.

After speaking to the resident who reported smelling smoke, “he got a key and opened the door to Apartment A. That’s when the bodies were discovered,” Boyd said.
