Investigators say the case started coming together this week after security staff reported James acting suspiciously Monday night. An employee later recognized him in surveillance video from the night of the killing wearing what appeared to be a long wig. Exclusive video shows armed officers arresting James in Rockville on Tuesday.

James is also accused of firing at a Maryland state trooper during a traffic stop in Baltimore. FOX 5’s Melanie Alnwick says ballistics testing linked the bullet that killed Fuller to the round fired at the trooper, according to charging documents. The trooper was not hit.

Detectives say James had been inside Fuller’s apartment the evening of Feb. 13 to administer medication. Fuller, a retired Navy officer and attorney from Augusta, Maine, was widely known for his philanthropic work. He was found dead in his bed the next morning with a gunshot wound to the head.

Charging documents also allege James tampered with security systems before the shooting, disabling alarms and propping open exterior doors.

A spokesperson for Cogir Senior Living says the facility is fully cooperating with investigators.
