District Attorney Lynne Abraham warned Philadelphians who plan to shoot guns in the air tonight to celebrate the New Year that they face aggressive prosecution if caught.

Joined at a late-morning news conference by Joseph Jaskolka, who on New Year's Eve in 1998 was struck and disabled by a falling bullet, Abraham also warned revelers of the devastating costs of the dangerous tradition.

"This is a sobering message on what should be a night of celebration," Abraham said.

She delivered the same message last year, and that night police received 402 reports of gunfire or someone with a gun, and officers arrested 19 people.

Jaskolka was 11 when he was struck in the head with a bullet in South Philadelphia. Now 20, he uses a wheelchair and attends Delaware Technical and Community College.

The gunman was never identified.
