Serena and Venus Williams lost their eldest sister, Yetunde Price, in a tragic killing in their hometown of Compton, Calif., over two decades ago.

The tennis stars grew up as the youngest of their parents’, Oracene Price and Richard Williams, five girls. Oracene welcomed her three elder daughters — Yetunde, Lyndrea and Isha — in her previous marriage.

Tragedy struck the family on Sept. 14, 2003, when Price was killed by a gunshot that seemed to come from nowhere — cracking through a window of her white SUV and hitting her in the back of the head, per the Los Angeles Times. She was 31 years old.

In an interview with PEOPLE in 2007, Serena said it was “still hard” for her to talk about.

“Yetunde and I were so close; she changed my diapers,” the tennis legend said. “But I finally came to an acceptance of things.”

Here’s everything to know about Serena and Venus Williams’ oldest sister and her untimely death in 2003.

Who was Yetunde Price?

Price was a nurse, mother of three and part owner of a modest hair salon. She also worked as a personal assistant to Serena and Venus, keeping track of their appointments and the like, even joining them at Wimbledon. But she mainly led a largely independent life in California.

In an interview with PEOPLE in August 2003, shortly before she died, Price seemed to have no regrets about steering clear of the slipstream of her famous kin. “They’re still my sisters,” she said. “We don’t get into the fame thing too much when we’re all together as a family.”

Price lived in a comfortable home in an upscale neighborhood in Corona. According to locals, she doted on her three kids, two boys and a girl, all of whom were under the age of 12 when she was killed.

How did Serena and Venus Williams’ oldest sister, Yetunde Price, die?

Price’s partner, Rolland Wormley, told the Los Angeles Times in 2003 that he had been at a picnic the day she died, and she came to pick him up after he lost track of time that night.

Price and Wormley switched spots, with the latter taking the wheel. Wormley later recalled the shooting as a burst of chaos during their drive back from Compton, Calif., to Price’s half-a-million dollar home in Corona some 40 miles to the east.

She’d been shot about a mile and a half from the tennis courts where her younger sisters learned to play the sport that made them stars.

“I’m trying to get through this. I’m trying to get away, I’m trying to get her to safety,” Wormley told the Los Angeles Times. “Once I get to Long Beach Boulevard, I see the back window is shattered. I look to the right and said, ‘Baby, are you all right?’ I look at [Price], and there was blood everywhere.”

Frantic, Wormley took Price to his mother’s house not far away, where she called 911. Price was pronounced dead at an area hospital not long after.

Who killed Yetunde Price?

In the first hours and days afterward, it remained unclear exactly what happened, with witnesses giving differing accounts that suggested there had been an altercation before the shooting that involved Price and Wormley.

In fact, investigators would learn the gunman had opened fire on their vehicle as they drove down the boulevard by a suspected drug house. Wormley maintained the attack was unprovoked, though prosecutors argued the shooting was revenge against another gang.

Apprehension of the accused was no less fraught: While one of the alleged shooters was taken into custody within hours, the second, Robert Edward Maxfield, was not caught until January 2004, following months of tracking by law enforcement, per The New York Times.

Maxfield, whom police said was a member of the Southside Crips, was arrested in a raid in Athens, Calif. He was unsuccessfully tried twice for murder before pleading no contest to a lesser charge just before the start of his third trial. (A no-contest plea essentially has the same effect as a guilty plea, but the defendant does not admit the accusations against them.)

In April 2006, nearly three years after Price was shot, Maxfield was sentenced to 15 years in prison for voluntary manslaughter, with credit for the time he had already served behind bars.

In March 2018, he was released on parole. Then, he was arrested again in Compton for allegedly violating his parole. Efforts to reach him directly or a previous attorney in his case were unsuccessful.

Speaking generally, a spokesman for the state’s Department of Corrections and Rehabilitation told PEOPLE that someone who violates their parole then goes before a judge could have their parole revoked, at which point they would be sent back to jail.

The DOC’s Luis Patiño confirmed at the time that the possible parole violation was being investigated.

Serena appeared at Maxfield’s court hearings for the first time when he was sentenced in 2006. According to the Times, she told him that, while she hadn’t planned to speak “because it’s too hard for me,” she felt it was more important to say how “unfair” Price’s killing had been “to our family.”

“Our family has always been positive and we always try to help people,” she said.

How did Venus and Serena Williams respond to the news of their sister’s death?

Venus and Serena were both out of town when they got the call that their sister was shot and killed.

“When [Venus and Serena] received the calls from all of us here, they were saying, ‘Are you sure this is correct?’ They couldn’t believe it,” a spokeswoman for the family told PEOPLE in the days after Price died.

The Williams’ sister’s sudden death sent shockwaves through the close-knit family. Venus got the news in New York City, where she was visiting for Fashion Week. Serena was in Toronto filming for the cable series Street Time and, by one account, became visibly distraught when she learned her sister had been fatally shot. Both flew to L.A., where they were joined by their parents.

The Williams family grieved and healed — slowly. “She was a wonderful person,” Serena said in 2004. “We’re dealing with it however we can. Some days are better than others.”

How have Serena and Venus Williams honored their sister’s legacy?

Years later, Price’s spirit remains strong both in her family and the community where they grew up. Serena and Venus opened the Yetunde Price Resource Center in Compton in late 2016.

“We definitely wanted to honor our sister’s memory because she was a great sister; she was our oldest sister, and, obviously, she meant a lot to us,” Serena said then, according to The Root.

She continued, “And it meant a lot to us, to myself and to Venus and my other sisters as well, Isha and Lyndrea, that we’ve been wanting to do something for years in memory of her, especially the way it happened, a violent crime.”
