Police in Alabama say a drive-by shooting killed a 13-year-old who was playing on his iPad in his bedroom, and they need help from neighbors.

Tuscaloosa police did not release the name of the boy who was hit in the head Friday by a bullet that went through his window, news outlets report.

There were so many shell casings in the road that officers used folded business cards as temporary evidence markers, police said on Facebook.

Investigators are looking for multiple people and cars, Captain Marty Sellers told WBRC-TV, asking witnesses for tips.

“It was early evening, so it was not dark outside, so people saw things and we just need them to step forward. Imagine if it was your family,” he said.
