A Levittown man who police and prosecutors said beat and shot at his landlord during a rent-related dispute last year -- sparking a two-hour standoff with Nassau police -- has been convicted of second-degree attempted murder and other charges, authorities said.

Nassau County jurors on Thursday convicted Rohan Kahn, 59 of that charge as well as first-degree reckless endangerment, third-degree assault and fourth-degree criminal possession of a weapon at trial.

"In an outburst of outrageous violence, this defendant beat and shot at his landlord, injuring him and a passerby, and endangering everyone in the area," said acting Nassau District Attorney Madeline Singas in a statement after the jury deliberated for two days.

Kahn faces up to 25 years in prison and is scheduled to be sentenced by acting Supreme Court Justice Meryl Berkowitz on Sept. 4.

His attorney could not be reached for comment.

In February 2014, Kahn assaulted, chased and shot as many as five times at his landlord as the victim was trying to collect rent, prosecutors said. Kahn then barricaded himself in his Carter Lane home before surrendering after a two-hour standoff with police, police said.

During the standoff, the Island Trees school district was placed on lockdown as Nassau County Emergency Service Unit, Bureau of Special Operations, K-9, aviation and hostage negotiation officers flooded the area. The standoff ended when Kahn surrendered.

Singas added in the statement that "rifle rounds struck the victim's car as he hid behind it, causing window glass to shatter and injure his face. Shattered windshield glass also injured a 54-year-old woman driving by, when Kahn shot into her car as the landlord tried to enter her car for safety."
