Three District men were found guilty Thursday of more than a dozen offenses, including witness intimidation and retaliation, in connection with a 2007 murder trial.

The D.C. Superior Court jury found Leroy Green, 23, Jermaine Scales, 26 and Darius Styles, 26, guilty of charges including conspiracy to obstruct justice,assault with intent to kill and aggravated assault.

Each faces up to 30 years in prison. Sentencing is scheduled for February.

Green saw someone who testified against him in a murder trial — he was acquitted — on July 29, 2009, according to prosecutors. Green shot the witness and another man on Minnesota Ave. SE. The witness was hit five times in his legs and the other man in the stomach, prosecutors said, but both survived.

An investigation revealed the shootings were connected to the 2007 fatal shooting of Royell Walker in Southeast D.C., with which Green was charged and later acquitted.

Prosecutors say Green, Scales and Styles also participated in a drive-by shooting in an attempt to kill a witness who was standing in the 3400 block of B Street SE. Three bystanders were struck and injured in that shooting.
