“What we know at this time is that there was a knock at the door. No descriptions of any persons at the door, one shot was fired,” said Deputy Commissioner Melvin Singleton following the shooting, according to the report. “We do have on the porch of the location one 9mm shell casing and that’s all we know at this particular point in time.”

Clark-Harrison was struck in the face, according to CBS. He died at the scene.

His mother, Lisa Clark, said she was home at the time and heard an adult male voice calling the boy’s name from outside the door, the outlet reported.

“‘Sadeek! Sadeek!’ she reportedly recalled hearing. “So, he was coming outside to answer the door because they were calling his name and he didn’t even open the door. He looked at the top of the door and they shot him through his eye.”

No arrests have been reported so far. Philadelphia police did not immediately respond to Fox News's request for information.
