Shelton police are looking into multiple theories on what led to 15-year-old Kristjan Ndoj being shot in an Agawam Trail driveway on Saturday night.

“Right now we’re not ruling anything out,” Police Lt. Robert Kozlowsky said on Monday morning. “We’re following several leads.”

Ndoj is in critical condition at Bridgeport Hospital, suffering from two gunshot wounds.

After completing the crime scene investigation on Sunday, Kozlowsky said, police now are doing interviews and re-interviews with people who may know more about the situation.

The goal, he said, is to “figure out why and who.”

Anyone with information on the incident is asked to call the Shelton Police Department at 203-924-1544.
