The Office of the Chief Medical Examiner in Boston has ruled that the death of Dr. Daniel Arnett, a 44-year-old cardiologist who disappeared during a bike ride, was a suicide caused by a gunshot wound to the head, the office told The Post. Investigators had earlier said they did not suspect foul play.

Arnett was last seen riding his bicycle in Newbury at about 10 a.m. on Saturday. His body was found shortly after 2 p.m. the following day near the cow pasture at Tendercrop Farm. He had practiced as a cardiologist with Beth Israel Lahey Health since 2021, and according to Doximity his specialties included echocardiography, cardiac CT, nuclear cardiology and preventive cardiology.S1S2
