St. Paul rapper Micheal “Eyedea” Larsen, who was found dead over the weekend, did not die as a result of trauma, authorities said.

The Ramsey County medical examiner’s office conducted an autopsy and no trauma was found, said Don Gorrie, the office’s chief investigator. The cause and manner of Larsen’s death are pending toxicology tests, which could take six to eight weeks, he said.

As half of the hip-hop duo Eyedea and Abilities, Larsen, 28, released several albums for Minneapolis label Rhymesayers and collaborated with nationally known artists such as Sage Francis, Aesop Rock and Atmosphere’s Slug. He also led the freestyle jazz group Face Candy.

St. Paul police were sent to Larsen’s apartment in the 300 block of Laurel Avenue about 11:40 p.m. Saturday. Paramedics were already there.

Larsen’s friends had tried to contact the man after he missed open-mike night that evening, and they came to the apartment to check on him when they couldn’t reach him, police spokesman Andy Skoogman said. Larsen’s mother, Kathy Averill, had a key to the apartment and they went in, Skoogman said.

They found Larsen’s body in his bed, Skoogman said.

Averill has set up a Facebook page in his honor and to raise money for a memorial service. — Ross Raihala and Mara H. Gottfried
