A Landover man who was convicted in January of first-degree murder — after having been previously acquitted of two separate murders — has been sentenced to life in prison, State’s Attorney Angela A. Alsobrooks said.

Circuit Court Judge C. Philip Nichols Jr. imposed the sentence Friday on Jacob L. Brooks, 21. In January , a Circuit Court jury convicted Brooks of murdering Daryl T. Clark, 36, on Nov. 3, 2008.

Nichols also sentenced Brooks to 20 years in prison for using a handgun in the commission of a felony, and five years in prison for a handgun violation. All of the sentences are to be served concurrently.

Clark was shot three times while he was walking his dog in the 1800 block of Cedarwood Court in Hyattsville. At the time of the killing, police said Clark was the victim of a robbery attempt.

Four days after Clark was killed, Brooks was arrested for carjacking a woman in Landover. Police found the gun used to kill Clark in the stolen Pontiac Grand Prix, according to testimony from Brooks’s trial for killing Clark. Brooks was convicted of armed carjacking, and is serving 23 years in prison for that crime.

In 2007, two different juries acquitted Brooks of murder in two separate trials.

In one trial, Brooks was acquitted of first-degree murder int he 2005 slaying of Lakita Danielle Tolson, 19,who was shot to death outside a Temple Hills nightclub.

Also in 2007, a jury acquitted Brooks of the 2006 killing of a longtime friend, Eric S. Holland. Prosecutors accused Brooks of killing Holland, who was 18, because Holland was cooperating with police in the investigation of the Tolson murder.
