Justin Martin — who co-starred with Zac Efron in ‘High School Musical 3‘ — will be locked up for 18 months after pleading guilty to 5 gun charges … TMZ has learned.
The Suffolk County D.A.’s office tells us Martin appeared in court Tuesday for sentencing. In addition to the jail time … he also got one year probation, during which he has to lay off drugs and booze and stay away from the scene of the crime.
As we reported back in July … Martin ran away from cops in Boston and pointed a gun at officers before he was chased and captured. He pled guilty to assault with a dangerous weapon, illegal possession of a gun and ammunition, carrying a loaded gun and firing a gun near a building.
Martin avoided a stiffer penalty — the D.A. was gunning to lock him up for 3 years.
