Murder suspect Jerry “Mike” Ramirez was ordered held without bail yesterday at the request of Caledonia County State’s Attorney Jessica Zaleski. Ramirez, 35, of Brooklyn, N.Y., who is facing a possible life sentence if convicted, pleaded not guilty at his arraignment in front of Judge Justin Jiron to charges of aggravated assault and 2nd-degree murder. Ramirez is accused of shooting and killing St. Johnsbury resident Vincent Keithan, 44, in the parking lot of Northeastern Vermont Regional Hospital in St. Johnsbury on Tuesday, March 1. “Mr. Ramirez had hunted him for over six hours in the early morning hours of that day,” said State’s Attorney Zaleski. “Multiple firearms have been recovered in this case to include a handgun matching the caliber of the projectile removed from Mr. Keithan’s head.” Zaleski then urged the judge to keep Ramirez behind bars for public safety reasons. “It is crucial to note that the state’s position here is that Mr. Ramirez poses a significant risk to public safety – both for witnesses who have been brave enough to come forward in this matter and the public,” said Zaleski. Judge Jiron granted that state’s request to keep Ramirez in pre-trial detention after Ramirez’s court-appointed defense attorney Dan Maguire of Essex told the court he needed more time to prepare before arguing for his client’s release.
