Suspect in stranger-on-stranger robbery & assault pleads guilty, receives 90 month prison sentence

Today, Multnomah County District Attorney Rod Underhill announced that 22-year-old Ashenafi Sisay Tingley received a 90 month prison sentence for assaulting and robbing a woman in the Pearl District.

The victim provided this office with an impact statement that was read in court: “I was physically injured by Mr. Tingley’s actions and will likely suffer some level of fear and emotional damage into the future. But, I am resilient and am lucky to have the support to move forward. I appreciate that Mr. Tingley has taken responsibility for and admitted to his actions and I hope that he will use the time in prison to rehabilitate himself and find a better path for his future upon his release.”

On October 19, 2019, Portland Police arrested Tingley near Mall 205 in southeast Portland for an unrelated matter. During the arrest, police found property belonging to a woman who lived in the Pearl District. Three days earlier, the woman reported being robbed and assaulted by a person in northwest Portland who matched the physical description of Tingley.

Detectives assigned to the Portland Police Bureau’s Robbery Unit reviewed the police reports associated to the October 16, 2019 robbery and learned that the woman and her friends had been hanging out at a bar in the 500 block of Northwest 16th Avenue. While the woman walked home, a stranger, later identified as Tingley, approached an assaulted her, which resulted in a serious head injury.

In response to being confronted, Tingley pointed a gun at one of the victim’s friends.

Tingley then ran from the area. Officers who responded to the initial robbery and assault searched the area looking for anyone who matched Tingley’s description but could not locate anyone.

When questioned by police, Tingley confessed to using a weapon that he described as a BB gun to steal the victim’s purse and that when she resisted, he pointed the weapon at her and then hit her in the head with it. He also admitted to pointing the weapon at her friend who chased him.

Tingley described the weapon he used during the commission of these crimes as resembling a Glock handgun.

Tingley pleaded guilty to one count of assault in the second degree, one count of robbery in the first degree and one count of robbery in the second degree. The court order Tingley pay $3,568 in restitution.

Upon his release, Tingley will be on three years of post-prison supervision.

This case was prosecuted by Multnomah County Senior Deputy District Attorney David Hannon.
