A Quincy man who spearheaded an effort to toughen the state’s criminal laws after the murder of his daughter is exploring a run for the Massachusetts Senate.
Les Gosule fought for more than a decade to persuade lawmakers to approve a bill overhauling the state’s sentencing guidelines, including a so-called three strikes provision barring parole for habitual offenders.
Gov. Deval Patrick signed the law last year.
Gosule began pushing for the sentencing changes after his daughter Melissa was raped and killed in 1999 by Michael Gentile of Halifax, who had 27 prior convictions.
Gosule, a Republican, says he’s eyeing the Norfolk and Plymouth senate seat currently held by Democratic state Sen. John Keenan of Quincy.
Republicans, who currently hold just three seats in the state Senate, are hoping to add to their numbers in the 2014 elections.
