Deante Strickland’s sister was indicted by a grand jury Monday in connection with his death earlier this month, according to Multnomah County District Attorney Rod Underhill.

The 22-year-old was a two-sport athlete at Portland State University and a former standout at Central Catholic High School.

Tamena Strickland, 30, was charged with one count of murder with a firearm, two counts of attempted murder with a firearm, one count of assault in the first degree with a firearm, one count of assault in the second degree with a firearm, three counts of unlawful use of a weapon and six counts of recklessly endangering another person.

On Aug. 2, Portland police responded to reports of a shooting in a home in the 6200 block of Northeast 42nd Avenue in Portland. When they arrived, they found Deante Strickland had been shot in his chest. Officers also located two women suffering from gunshot-related injuries. Both were transported to the hospital.

Authorities have declined to identify the women, but family members have identified them to The Oregonian/OregonLive as Tamena Strickland’s grandmother Shirley Strickland, 67, and her 25-year-old aunt, whose name is also Shirley Strickland.

According to court documents, Deante Strickland and the elder Shirley Strickland were inside the living room when the shooting occurred. Strickland’s aunt told police that when she heard gunshots, she left her bedroom inside the residence and approached the living room, where Tamena Strickland aimed a silver handgun in her direction and shot her.

The indictment alleged that Tamena Strickland unlawfully and recklessly created a substantial risk of serious physical injury to six people. She surrendered to police, with her attorney, later that night.

During their investigation, detectives searched a car associated with Tamena Strickland and found a black gun box on the front passenger seat floorboard, according to court documents.

She is scheduled to be arraigned Tuesday in the Multnomah County Justice Center.
