'Copper' star Ato Essandoh joins 'Elementary'

Ato Essandoh, who plays Civil War-era Dr. Matthew Freeman on "Copper" is time-traveling to modern-day New York City for a guest spot on "Elementary."

According to CBS, Essandoh will play Alfredo, a streetwise recovering addict with a special talent for stealing cars. Alfredo will cross paths with Holmes (Jonny Lee Miller) and Watson (Lucy Liu) at a support group meeting, where his tough insightfulness will surprise them both.

Essandoh's Dr. Freeman on "Copper" is himself a skilled sleuth, acting as an informal coroner/crime scene investigator for Detective Kevin Corcoran (Tom Weston-Jones) in New York's dangerous Five Points neighborhood.

"Elementary" airs Thursdays at 10 p.m. on CBS, and you can catch "Copper" Sundays at 10 p.m. on BBC America.
