MEDFORD - A doctor accused of providing drugs to the man behind the Medford massacre has been arrested.

Both David Laffer and his wife were patients of Dr. Stan Xuhui Li, who has been charged with illegally selling prescription drugs out of his clinic in Flushing.

Li was picked up Saturday at his office at Medical Pain Management. He was also an anesthesiosologist at a New Jersey hospital.

Prosecutors say Li made approximately $450,000 in cash from the illegal sales. He's being held on $500,000 bond and is due back in court next month.
