A D.C. jury has found a 26-year-old District man guilty of killing two men and wounding another at an illegal craps game in Northwest Washington.
Irving Harris Johnson, 26, was found guilty of a total of 15 charges following a two-week trial, including shooting at a fourth man in a separate attack.
Johnson could face more than 100 years in prison for the various offenses.
According to prosecutors, the violence stemmed from a long-standing dispute between Johnson and the victims.
According to authorities, during the early morning hours of July 9, 2011, Johnson walked up on a craps game in the 1400 block of Parkwood Place NW and opened fire. Jimmie Lee Simmons III, 32, and Domonique Barber, 31, died at the scene. A third person, Anthony Thomas, then 21, survived bullet wounds to the chest and head. But after a year of struggling from the injuries inflicted by the defendant, the third victim took his own life, prosecutors said.
It wasn't the first time Johnson has been arrested in a homicide.
In November 2005, police arrested him for the death of 16-year-old Erica Anderson.
Johnson, then 19, was playing with a loaded handgun with several teenage friends at an apartment in the 3500 block of 14th Street in Columbia Heights, police said.
The gun went off and Anderson, a Bell Multicultural High School student, was shot in the face, police said.
Johnson said it was an accident. Prosecutors said there wasn't enough evidence to go forward with charges, and Johnson was released before the case was presented to a judge, court records show.
No charges were filed in Anderson's death.
