After four days of interviewing more than 200 prospective jurors, a jury of 12 District men and women and five alternates was finalized Thursday for the trial of five men charged with a series of fatal shootings in 2010.

The trial, which is expected to last about three months, is scheduled to begin Tuesday with opening statements from five of six defense attorneys and one of three prosecutors.

Prosecutors said they expect to call more than 100 witnesses and show about 1,000 pieces of evidence. Defense attorneys expect to call about a dozen witnesses themselves.

Security in Courtroom 302 in D.C. Superior Court is expected to be heightened for the trial as friends and families of the victims — five people were killed in the shootings, and others were hurt — sit among friends and family members of the accused.

Orlando Carter, 22; his brother, Sanquan, 21; Jeffrey D. Best, 23; Robert Bost, 23; and Lamar Williams, 23, are charged with first-degree murder and other offenses in the attacks.

The Carter brothers, Best and Williams are charged in the shooting death of Jordan Howe, 20, on March 22, 2010, in the 1300 block of Alabama Avenue SE. Prosecutors say Howe’s friends shot Orlando Carter the next day.

On March 30, the day of Howe’s funeral, prosecutors say Orlando Carter, Best and Bost shot and killed Tavon Nelson, 17, while trying to steal a gun. They then opened fire from a rented minivan in the 4000 block of South Capitol Street with an AK-47-style assault weapon and a .45-caliber semi-automatic pistol, prosecutors say, killing three people who had attended Howe’s funeral — Brishell Jones, 16, Davaughn Boyd, 19, and William Jones, 19.
