PROVIDENCE, R.I. (AP) — A Rhode Island man has pleaded not guilty to murder in the death of a former chiropractor.

Owen Morris entered his plea Wednesday during his arraignment hearing. The 21-year-old Warren man is accused of stabbing chiropractor Clive Bridgham to death.

Police found 67-year-old Bridgham dead in his East Providence home Jan. 11. Authorities have described the killing as "particularly brutal."

Morris and other patients had filed a complaint in 2016 alleging Bridgham violated professional boundaries. He surrendered his license as a result.

An attorney for Morris declined to comment after Wednesday's hearing. Morris is being held without bail.
