A California fire department is facing criticism after offering an AR-15 rifle as a raffle prize at a fundraiser just days after police said a 19-year-old used the same weapon to gun down 17 people at a high school in Florida.

Allison Merrill told the Sacramento Bee that she was so offended by the gun, which was raffled Saturday during the Cameron Park Fire Department's crab feed, that she and her friends walked out of the event.

"When we walked out, the flag was at half-mast in front of the community center, and it was just so striking, how tone-deaf the whole event was," she told the Bee. "We walk out and there's the flag at half-mast for all those kids."

Police believe the shooter in last week’s deadly attack in Parkland, Florida, used an AR-15 when he killed 14 students and three teachers at Marjory Stoneman Douglas High School.

"To have our first responders be the ones kind of offering a military-style assault rifle as a prize – putting that out into our community, especially right now – it was appalling," Merrill told KOVR.

Merrill told the news station that she spoke with the fire chief, who apologized and acknowledged that the gun raffle could be seen as insensitive. She told the Bee that event organizers refunded her and each of her three friends the $40 fee for the event, although she added to KCRA that "the money wasn't really an issue."

“I was deeply disturbed by it,” Nancy Lugo, who attended the event with Merrill, told the Bee. “Not only the timing of the recent shootings but also the fact that it’s that easy to get an AR-15.”

Cal Fire spokesman Scott McLean told KCRA that the Cameron Park Fire Department has held similar fundraisers since 2002. The fire department is under contract with Cal Fire, according to KCRA.

“These weapons are not any different than anything you could go into the gun store and buy,” McLean told the Bee, adding that the fundraiser was planned before last week’s deadly shooting.

The gun was taken to a gun store after the raffle, McLean said, where it will stay for a 10-day waiting period required by law as officials run background checks to ensure the winner of the raffle can legally own the firearm.

"I understand the concerns, by all means," McLean told KCRA. "No harm was intended."
