SAN DIEGO (CNS) - A young man who fatally stabbed an Ocean Beach transient was convicted Friday of second-degree murder.

Noah Mitchell Jackson, 21, was found guilty in the June 22, 2017, killing of 65-year-old Walter "Ras" Riley. Jackson is slated to be sentenced on Aug. 23.

The victim -- an Ohio native nicknamed "the Incense Man" due to his practice of selling aromatic burning sticks at local farmers' markets -- was stabbed just before 12:30 a.m. that day. Witnesses called 911 reporting that a man was attacking another man in the 1900 block of Bacon Street.

Responding officers found Riley lying on the sidewalk with stab wounds to his upper body. He was pronounced dead at UCSD Medical Center.

Deputy District Attorney Michael Reilly said the victim was stabbed five times, with the killing blow entering his back, breaking several ribs and puncturing his heart.

Jackson confessed to a friend that he stabbed Riley, according to the prosecutor, who alleged Jackson told the friend, "I got that guy. I stabbed that (expletive)."

"Those are the words of a murderer," Reilly told the jury.

Reilly said that some time after the killing, Jackson had a friend drive him to Kellogg's Beach, where Jackson threw the murder weapon and his cellphone into the water. Police divers were not able to recover the knife or the phone.

Jackson's attorney, Eugene Iredale, alleged the friend was pressured by police to incriminate Jackson and was being offered immunity for his testimony in the trial.

According to Reilly, Jackson told police that he was home and asleep by 9:30 p.m. the night of the stabbing, but later confessed to another friend that he lied to police and went back out to confront the victim, though he denied fighting or stabbing him.

Reilly alleged that Jackson also told the friend that he "handled" the victim because Riley had previously spat on Jackson's sister and insulted her. However, Iredale denied this alleged motive, as he said his client had substance abuse problems that led him to make several "completely random statements" to friends following the date of the killing. The attorney said the spitting incident involving Jackson's sister never occurred and "God only knows" why he said it.

Iredale alleged that police originally had 20 to 30 suspects, but centered on Jackson due to a 911 call made about 90 minutes prior to Riley's stabbing.

In that call, a recording of which was played for the jury, the mother of one of Jackson's friends said Jackson was at her home displaying erratic behavior and was saying he wanted to commit suicide. He'd just gotten into an argument with his girlfriend, then left the house, she told a dispatcher.

Iredale alleged the clothing description she provided police -- a white sweatshirt and jeans -- vaguely resembled the attire of a suspect captured on surveillance footage running through Ocean Beach following the killing. That footage was publicly released shortly after Riley's death.

Iredale said the man in the footage was Riley's killer, but looked nothing like his client.

Jackson was arrested in Huntington Beach in February 2018 by SDPD detectives with the help of local police and the U.S. Marshals Service.
