The Boulder County Coroner's Office said the homeless man found dead on the University of Colorado campus in April died of blunt trauma injuries to the head and chest and ruled his manner of death "undetermined."

Ralph DeVore, 51, was found near the intersection of College Avenue and Broadway on April 5.

Devore was a transient, according to CU police, who, at the time of his death, indicated there were no signs of foul play or any ongoing threat.

CU detectives could not be reached Monday, and it is unclear what the coroner's ruling means for the investigation into DeVore's death.

DeVore was one of four homeless people whose bodies were found outdoors in Boulder over a five-week span in April and May, and the second death to be ruled as "undetermined" by Boulder County Coroner Emma Hall.

Hall ruled the cause and manner of death for Thomas Cornell, a homeless man whose body was found in a drainage ditch behind the Boulder Target store, also "undetermined."

Janice Adams, a Boulder homeless woman found dead in April along Boulder Creek, died of alcohol poisoning while Hall has not yet released a cause and manner of death for Kathryn J. Fishman, who was found dead at Scott Carpenter Park.
