Jefferson Parish Sheriff Joseph Lopinto said the boy was hospitalized in critical condition Friday afternoon, news outlets reported.
Lopinto said the officer was asleep when he heard noises outside his home around 3 a.m. Friday in the New Orleans suburb of Metairie. The man went outside and saw several juveniles in his front yard, near his vehicle, authorities said.
An altercation occurred and the man shot the 14-year-old in the head, Lopinto said. The other individuals fled the scene but were later identified and interviewed, Lopinto said.
