The latest incentive to solve the crime is in addition to an earlier $2,500 reward via Crime Stoppers.

PORTLAND, Ore. — A $30,000 reward has been offered by the father of Cody B. Oller, 25, who was shot dead Jan. 8 in Northeast Portland's Fernhill Park.

"We just really felt like if a reward is what moves us to the next place in this investigation and leads to some sort of explanation for the last moments of his life then it's worth anything we have," Jamie Oller, Cody's sister said.

The latest incentive to solve the crime is in addition to an earlier $2,500 reward via Crime Stoppers.

Oller, originally from Kansas, died from a gunshot wound, according to the Oregon State Medical Examiner's Office. Police said Oller's manner of death was homicide.

"We really can't imagine who would want to hurt him," Oller said. "He's the type of guy who would give you the shirt off his back."

Officers responded to a report of gunfire at the park, at 6010 NE 37th Ave., around 9:30 p.m. They found Oller dead on the ground. There is no suspect information.

Hours after Oller's death, social media in Portland circulated posts that self-made rap music promoter Kool Aid was the victim. He had to post a Facebook video of himself alive the next day to quell the rumors.
