The atmosphere at Istrouma High School was solemn Friday as students mourned the shooting death of an 18-year-old senior, the school’s principal said.

Darren Smart, 18, 3463 Fairwoods Drive, was shot and killed Thursday while attempting to run into a house at 4752 Bradley St. around 7:30 p.m., according to a Baton Rouge Police Department news release.

“Everyone is saddened by (Smart’s) death,” Istrouma Principal Linda Lewis said. “He was a good student, a polite young man.”

Lewis said Istrouma’s guidance counselors worked with students throughout the day to help them grieve the loss.

“The senior class is very saddened by his death,” she said.

Police believe the shooting might be related to a fight that occurred last week.

Two men rode bicycles past the house on Bradley Street numerous times before stopping and shooting at a group of men who were standing outside, police spokesman Cpl. L’Jean McKneely said in the release.

Police found Smart’s body inside the house when they arrived, McKneely said.

Linda Smart, Darren Smart’s mother, said Darren was a reserved person that was “quiet about everything.”

“He was somebody that kept to himself,” she said.

Linda Smart, 40, said she did not know what her son was doing the night of his death. She said her son spent most of his free time at home.

She said she believes her son was in the wrong place at the wrong time when he was shot.

“Everybody who knows him, they know he was humble,” Linda Smart said. “He was always smiling.”

This shooting comes about three months after another man was shot and killed in the same area, police have said.

Henry Thomas, 34, was fatally shot June 3 in the 4600 block of Bradley Street, McKneely has said.

Anyone with information about Darren Smart’s shooting is urged to contact the Baton Rouge Police Violent Crimes Division at (225) 389-4869 or Crime Stoppers at (225) 344-STOP.
