OAKLAND -- The last time 31-year-old Shemicka Johnson saw her younger sister, the teen was doing what she loved most: shopping.
"I ran into her leaving Southland mall with her boyfriend," Johnson recalled of her 18-year-old sibling, Ayana Dominguez. "She told me she was going to Dave & Buster's, I told her to have fun and she said she'd call me soon."
That call never came.
Two days later, her sister was dead. And on Wednesday, the Berkeley resident's slaying remained a mystery.
Dominguez died following a double shooting about 8:45 p.m. July 10 in the parking lot of a Wendy's restaurant in the city's Fruitvale district. The shooting also left her 22-year-old boyfriend wounded outside the 3100 International Blvd. eatery, police said.
Police said the two had driven to Wendy's for food and were sitting in the car when at least one gunman opened fire from outside the vehicle before fleeing. The boyfriend, an Oakland resident whose name was not released, refused assistance and was taken by relatives to a hospital in stable condition with a wound to his lower body.
Police learned that Dominguez had also been taken by passers-by to a hospital, where she died at 9:34 p.m.
"I got a phone call that she'd been shot," Johnson recalled. "You hear about it all the time, but you don't think it would happen to someone close to you."
Dominguez and her boyfriend had dated for about two years, Johnson said.
"He called me from the hospital the day after the shooting. He was just apologizing to me that he didn't call me. I just wanted to hear what happened. He sounded very sad. Angry. The same thing everybody is feeling. Who would do this?"
Dominguez graduated in February from the Berkeley Technology Academy, which is part of the Berkeley public school system, and had been an intern at the Association of Bay Area Governments in Oakland, her sister said.
Dominguez, an aspiring cosmetologist, excelled at hair braiding and hair design. Her favorite hobby was shopping.
"She had a bubbly personality," her sister said. "Was a real girly girl who loved make up and dressing up."
Kathleen Cha, senior communications officer at the Association of Bay Area Governments, said she worked closely with Dominguez while she interned at the agency for about one year, performing administrative duties.
She worked at the agency's Oakland office through a program called Highways to Work, funded by the Alameda County Department of Social Services that places at-risk youths in paid internships so they can develop work skills, Cha said.
"Not only are we sad, we're enraged because she's not a statistic. This is personal," Cha said. "She was a quick study. Very curious, shy and reserved, but it was fun to be able to watch her grow in her abilities."
Dominguez is survived by her mother, Autumn Blueford, her father, Scott Dominguez, two sisters and one brother, all from the East Bay.
A private memorial service will be held but a date had not been set as of Wednesday, Johnson said.
Police do not yet have a motive for the attack, and no arrests had been made. Police and Crime Stoppers of Oakland are offering up to $15,000 for information leading to the arrest of suspects. Anyone with information may call police at 510-238-3821 or Crime Stoppers at 510-777-8572.
