Rosendo Flores was 45 when he was found dead from a gunshot wound behind an apartment complex in the 4800 block of North Minnesota Avenue in Portland. His body was discovered on June 12, 1998; witnesses say a single shot was heard around 11:07 PM the night before and shortly afterward a man was seen leaving the area.The description given for that man is an African-American male, about 6 feet tall, slender build, short hair; he remains the only known potential suspect.

Flores was known locally as a horse breeder and trainer with property in Washington County and was reportedly involved in selling illegal drugs, a circumstance authorities think may have been relevant to his killing.No arrests have been made and the Portland Police Bureau Cold Case Homicide Unit continues to investigate.

If anyone has information about the man seen leaving the alley that night or about Flores’s activities in north Portland in June 1998, please come forward.
