News of a Los Angeles Dodgers fan fatally stabbed Wednesday night near AT&T Park after the San Francisco Giants game hits home to Bryan Stow's family and friends.
The attack comes just as the Giants began a three-game fundraiser for Stow, a Giants fan attacked at opening day at Dodgers Stadium two years ago.
Stow suffered a traumatic brain injury, and some ticket proceeds from the fundraisers are helping to pay for his medical bills.
On Wednesday night, 24-year-old Jonathan Denver, who had traveled to San Francisco from Fort Bragg, was fatally stabbed in what police are calling a rivalry-fueled fight that broke out near AT&T park.
Stow's family and friends are reacting to the latest episode of violence, calling it "senseless" and said they were shocked to learn that fan rivalry appears to have played a role in the attack.
Martine Bustamante, a former co-worker, said Stow used to light up the halls at Rural Metro with his smile and what she called an indescribable "spark."
"Another family is grieving, another life, unfortunately this time a life was lost," Bustamante said. "It's senseless, it should not happen."
News of another attack on a baseball fan stunned Stow's former paramedic partner Brian Green.
"It still hits home," Green said. "Especially with what happened yesterday, it just brings back all those memories of the tragedy with Bryan. To see the ill effects of what happened to Bryan, it's not good."
Stow's sister, Erin Collins, called the fatal stabbing senseless.
"We're heartbroken for Jon's family, and truly, we're keeping them in our prayers," she said.
