Minnesotan rapper Eyedea unexpectedly passed away last month, putting the hip-hop community into mourning. Over a month later, an autopsy has determined that the 28-year-old died of an accidental overdose, though the specific drugs discovered in his blood system have not been released to the public.

Eyedea's mother Kathy Averill discovered the emcee, whose real name is Michael Larsen, on Oct. 16 in his St. Paul apartment. The rapper had attended nightclub First Avenue & 7th Street Entry the prior evening to watch his longtime collaborator Abilities and L.A.'s Pigeon John perform, reportedly in good spirits by those who spoke with him.

Believing that he passed away in his sleep, Averill reported the news to fans by writing on her Facebook wall. "It is with great pain and sadness that I tell you my son Mikey (Eyedea) has passed away ... At this time we kindly request your respect and our privacy as we process this devastating loss. We do, however, welcome your kind words, memories, and positive thoughts," she wrote.

Family and friends celebrated Eyedea's life during a public wake on Oct. 29 at the Crown Street Plaza St. Pual-Riverfront Hotel. The emcee had a fruitful rap career, winning 1999's Scribble Jam MC battle and 2000's Blaze Battle. With former Atmosphere DJ Abilities, he released three full-length LPs as well as albums with other collectives. His last release was 2009's 'By the Throat.'
