ST. PETERSBURG — A young woman trying to make an evening snack ended up at the hospital Monday night after a round of ammunition exploded inside an oven, police said.

Eighteen-year-old Aalaya Walker just wanted some waffles.

What she didn't know was that her friend Javarski "JJ" Sandy, 25, had placed a magazine from his .45-caliber Glock 21 in the oven. It's unclear why he would do that.

The gun itself was inside a drawer, Sandy later told police.

Walker preheated the oven shortly after 9 p.m. She heard an explosion a short time later.

She picked fragments of at least one round from her chest and leg. She rode the bus to St. Anthony's Hospital, where she met with officers.

They sought out Sandy, who was at his apartment in the 200 block of 24th St. N.

Sandy, who has a permit to carry a concealed weapon, confirmed Walker's story.

He told authorities there were four rounds in the magazine. He showed the melted magazine to officers, though he'd already thrown away the other bullets.

"He stated that he does not have a temperature gauge on the oven so he estimates the temperature based on how far the knob is turned," an officer wrote in a report. "I observed that the inside of the oven was damaged."

Police described Walker's wounds as "superficial." They did not make any arrests.
