SYRACUSE - Syracuse University resumed a normal schedule after briefly warning students Monday to seek shelter and barricade their doors while police investigated a drive-by shooting near the upstate New York campus. University officials e-mailed the alert to its more than 19,000 full and part-time students as a precaution just after 11:30 a.m.

The alert was lifted about an hour later when police reported the shooting suspect was no longer in the area near the school.

Police said a 20-year-old man was sitting in a parked car several blocks from campus when another car drove by and someone fired multiple shots at him. The victim was hit in the neck and taken to Upstate Medical Center in critical condition, police said. Morrow said the victim was not a student.

Police were pursuing the gunman, who they said apparently targeted the victim.

Syracuse put its Orange alert system in place a little more than one year ago in response to the shootings at Virginia Tech in 2007. The system has been tested before, but this was the first time it was used in earnest, officials said.
