According to the search warrant affidavit:

Police were called to St. Mary’s Hospital about 8:30 a.m. on Sept. 12, about two hours after Sidener brought in Allen, who was dead.

An autopsy did not immediately determine the cause of death, which required additional toxicology tests. Last week, results from the tests showed that Allen had died from an overdose and had multiple drugs in her system, including heroin, fentanyl and a fentanyl analog, and cocaine.

Sidener told police that he had picked up Allen at a Far East Side motel the night of Sept. 11 and brought her to his home. He said they hung out all night, and she spent the night there. He said he and Allen used only marijuana and when he fell asleep between 1 and 2 a.m., Allen was fine.

When he woke up at 5 a.m., Sidener told police, he suspected Allen had possibly used heroin, that she was “breathing really weird” and her body “was like a pile of mush.” He told police he watched over her for about an hour, and when she didn’t improve he carried her to his car and drove her to St. Mary’s Hospital.
