DALLAS (CBSDFW.COM) – An 18-year-old was killed after a shooting in a parking garage just across from NorthPark Center mall late Thursday evening.

It was just after 10 p.m. when the shooting happened on the upper level of the Shops at Park Lane parking garage, just outside Dick’s Sporting Goods.

When officers arrived they found Joseph Anthony Pintucci slumped over in the driver’s seat of an older model white sedan. The victim was taken to nearby Texas Health Presbyterian Hospital but later died.

The shooting happened at a time when there should have been foot traffic in the area. There’s a nearby Whole Foods market that had closed just minutes earlier and also a number of restaurants and apartments nearby.

Police have not discussed a motive for the shooting, but in statements early Friday said they were  interviewing witnesses and looking for multiple suspects.

Administrators with the Highland Park Independent School District confirmed to CBS 11 News that Pintucci was previously a student at Highland Park High School but withdrew last school year.
