TAMPA, Fla. (AP) - A 17-year-old high school senior was fatally gunned down while playing dice in Tampa 16 years after his father was killed in an eerily similar scenario.

Jesse Patty says it's hard to comprehend burying a son and grandson. He said Byron Patty Jr. was playing dice Thursday when a gunman demanded money and shot Patty. He died at the hospital Saturday.

In 1994, 21-year-old Byron Patty Sr., was playing cards in Tampa motel when a gunman shot Patty twice in the chest during a struggle.

The grieving grandfather says he doesn't "understand how this could happen twice."
