Dyquain was 21 years old when he was last seen alive by his grandmother.
He had failed to show up for his management job that day and his family found his cell phone, wallet and classes at the house.
His final few Facebook posts suggest he was unhappy about something, with one posted on October 31st 2014 reading: "I have been having the worst luck lately." The next day was the last day he was seen alive.
One post, uploaded two weeks before on October 16th said: "People are acting strange lately and thats why im doing it for me not them."
Despite family and friends organising a number of search parties, they could not unpick the mysterious disappearance and the cops were in the dark too.
Erie police Lt. Julie Kemling told the Erie Times-News said: "It is one of the few cases around here that is a mystery."
It appears the body had been in the attic for two years.
Cops have said the death appears to be a suicide, but the investigation is continuing.
The family does not agree with the suggestion of it being a suicide, and Dyquain's aunt Erica Jeffries-Jordan told Erie Times-News: "I don't believe any of this stuff. I want answers."
