The hyperactive little Jack Russell terrier named Kaylee would chase anything thrown her way.

And to the horror of several adults and children at the Kolinoski family July 4 picnic, she did exactly that with a powerful firecracker thrown into her yard.

No charges, however, were expected to be filed in the death of the dog after the firecracker exploded in her mouth, authorities said Tuesday.

"I lost a family member," Joseph P. Kolinoski, 26, wrote in a statement to a sheriff's deputy.

He said later in a phone interview that he was grateful no one else was hurt.

"It could have been a lot worse," he said. "We had a lot of kids out there."

Kolinoski said the family had been celebrating in their yard on the 1000 block of Southeast St. Lucie Boulevard when his wife's uncle drove by and threw the explosive about 5:30 p.m.

"He wasn't even invited," the dog's owner said. "She's a Jack Russell terrier. ... They're hyper dogs. They think everything's a toy."

Kolinoski said the 3-year-old, 8-pound dog was blown to pieces and was buried shortly after the incident.
