Dondrique Lewis, a 28-year-old Slidell rapper, was sentenced to 15 years in prison Wednesday on two counts of attempted murder in the 2012 shootings of his half-brother, Damian Lewis, and a longtime friend, Andre Jackson, according to the 22nd Judicial District Attorney’s Office.

District Judge Scott Gardner sentenced Lewis to 15 years on the first count, without the benefit of parole, probation or suspension of sentence, and to 10 years on the second count, to be served concurrently.

Lewis was found guilty in November, spokeswoman Lisa Page said.

The two brothers were visiting their sister in Slidell on March 21, 2012, when a shot was fired. Damian Lewis, who had been standing outside, began running, Page said.

When he was about a block away, he realized Dondrique Lewis was running beside him, and he stopped.

At that point, Dondrique Lewis pulled a gun from behind his back and shot Damian Lewis in the back of the head as he tried to flee, Page said.

Dondrique Lewis then walked another two blocks, knocked on a door and shot Jackson when he answered, she said.

He was arrested the same day.

The motive for the shootings remains unclear, Page said. Both victims survived.
