Jeffrey Burnham, the Cumberland man charged with killing his brother, sister-in-law and an elderly family friend, allegedly wanted to confront his brother Brian Robinette, a pharmacist, because he believed the government is “poisoning people with COVID vaccines,” according to charging documents filed in the District Court of Maryland for Howard County.

Jeffrey Burnham, 46, is currently being held in the the Allegany County Detention Center. He’s charged with first-degree murder in the killing of 83-year-old Rebecca Reynolds, who was found dead Sept. 29 in a Cumberland home.

Prosecutors charged Burnham with two counts of first-degree murder, two counts of second-degree murder and one handgun charge in the death of his brother and Brian’s wife Kelly.
