The two reputed gang members pleaded not guilty Sept. 23, 2013 to the 1997 fatal shooting Johnis Demar Jackson on June 21, 1997.
Last year prosecutors contended Johnson fired the fatal shots. Jackson, a rival gang member, was shot while walking to his car near North Fair Oaks Avenue and West Harriet Street.
Earlier that day, Evans, who was Johnson's girlfriend at the time, confronted a friend of Jackson's over some CDs she said he had stolen, and the man slapped her, the Pasadena Star-News had reported. Investigators had several leads in the killing, but charges weren't filed until 2013 when new evidence surfaced, the newspaper reported.
Johnson was also involved in the Halloween 1993 killings of two 14-year- old boys and a 13-year-old boy who were trick-or-treating in northwest Pasadena. Johnson gave grand jury testimony implicating Aurelius Duane Bailey in the Halloween homicides, but his statements were not admitted in court. Bailey was sentenced to five years probation after pleading to voluntary manslaughter and attempted murder.
