Overview

• Kevin Monahan, 66, is on trial for second-degree murder in the death of 20-year-old Kaylin Gillis, who was shot after she and her friends mistakenly turned into Monahan's driveway.
• Monahan's defense attorney argues that the shooting was a 'terrible accident' involving a defective gun, claiming that Monahan fired a warning shot and the gun discharged a second time when he stumbled.
• Prosecutors argue that Monahan recklessly caused Gillis' death and later provided misleading information about the shooting.
• Gillis' friends called for help once they found a cellphone signal several miles away, but emergency workers were unable to save her.
• The trial, which is expected to last several weeks, has drawn significant attention and complicated jury selection.
