A Pennsylvania woman found the mummified remains of her grandson in her attic — two years after the man suddenly went missing, authorities said.

Zanobia Richmond discovered the corpse of Dyquain Rogers, 21 — who was reported missing in November 2014 — after she heard a thump on the top floor of her Erie County home, officials said. She called police immediately after making the gruesome find.

“They were mummified,” Erie County Coroner Lyell Cook told The Post of the remains. “The lack of airflow and the fact that the attic wasn’t vented — those conditions were optimal for dehydration and mummification.”

Officials did not release a cause of death, but sources said it appeared Rogers had hanged himself.

Cook, the county’s coroner of 16 years, said his office rarely sees cases involving mummified bodies.

“It is unusual, we don’t see much of that,” he said. “They’re very rare.”

Cook said there’s no evidence of foul play, saying there’s “nothing to suggest anything other than suicide” in the case. But some of Rogers’ relatives had to be convinced that he took his own life, including his aunt, who organized early efforts to find him when he originally disappeared.

Erica Jeffries-Jordan told the Erie Times-News on Thursday that she now accepts suicide as her nephew’s cause of death after initially calling for an autopsy, saying she “didn’t believe” that Rogers killed himself.

“I have to accept it now because that is what they said,” Jeffries-Jordan told the newspaper, referring to police, Cook and another one of Roger’s relatives. “I really don’t want to accept it.”

After questioning the initial suicide ruling on Wednesday, Rogers told the newspaper she no longer disputes Cook’s finding.

“I did all I could do,” she said. “I must accept it as it is.”

Cops who investigated the case back in November 2014 searched the inside and outside grounds of 2506 German St., where the body was found, according to reports in the case cited by detectives Thursday. But the reports do not indicate whether officers at the time checked the attic, the Erie Times-News reports.

“All indications are that [Rogers] wasn’t there when our guys were there,” Erie Police Chief Donald Dacus said of the original search. “He returned at some point wearing different clothing.”

Dacus said investigators believe Rogers’ body was in the attic for most of the time that he was missing.

“The difficult part is we will never have the answers,” he said.

Rogers, who graduated Central Career and Technical School in Erie in 2012, volunteered at a local fire department and worked as an assistant manager at a pizza shop in the western Pennsylvania town. His aunt said he didn’t appear suicidal and was looking into joining the Navy or to work as an emergency medical technician. Rogers had been “having the worst luck lately,” according to a Facebook post from Oct. 31, 2014 — just days before he was reported missing.

“If you are going to throw your life away, why are you going to do all these things?” Jeffries-Jordan told the Erie Times-News in March.
