GLASSBORO — Nine cops have been holed up in a hotel all week, learning to draw better and faster.

No, it’s nothing to do with their service weapons.

They’re attending a class on Digital Composites drawing, hosted by the Glassboro police department, at the Marriott on Rowan Boulevard.

Instructor Natalie Murry, from Texas, is taking the officers through their paces using the latest technical devices and software. (Below, with Ptl. Jamie Morris of Woodbury.)

Investigator Julie Howery (above left) said the department is hosting the weeklong workshop with the help of the Gloucester County Prosecutor’s Office and Fraternal Order of Police Lodge 108.

Most of the police artists or artists-in-training come from New Jersey, including a couple from the New JErsey State Police, but there are attendees from Loudoun County, Va. and Kalamazoo, Mich. in attendance.

Some of the training utilizes tablet computers which would allow an artist to draft a composite likeness of a suspect while in the field.

There’s no abracadabra involved, though. Despite the state-of-the-art gear and software, the officer still has to be able to draw the face as described by a witness — and hope for a likeness some member of the public will recognize.
