NEWARK — The last of six defendants convicted in a notorious schoolyard triple murder was sentenced Wednesday to 195 years in prison, closing one chapter on a crime whose savagery made national headlines and spurred numerous anticrime measures in New Jersey’s largest city.

What happened behind the Mount Vernon School on the night of Aug. 4, 2007, was ‘‘evil incarnate,’’ state Superior Court Judge Michael L. Ravin told the gallery as he sentenced Gerardo Gomez to three consecutive terms of 60 years each on three murder counts and 15 more years on an attempted murder count.
