A Baker man was shot and killed by a police officer in Miami-Dade County on Wednesday after he kidnapped his ex-wife and pointed a gun at an officer responding to her call for help, authorities said.

Francis Scot Dufore, 41, drove from Louisiana in a stolen vehicle to Homestead, Florida, where he contacted his ex-wife at a grocery store about 6 p.m., according to a Miami-Dade police news release. He then ordered the woman at gunpoint to get into the vehicle, police said.

While in the vehicle, Dufore choked the victim in the back seat until she lost consciousness and then drove away, a few miles into the woods, the release said.

When she recovered consciousness, she found herself in a wooded area with Dufore out of sight. She was able to find her cellphone and call 911, the Miami Herald reported.

Miami-Dade police responded, located an unoccupied vehicle with its trunk open and began to search the area, the release said.

Dufore appeared and pointed a shotgun at an officer who confronted him, forcing the officer to shoot, the release said.

Dufore, 3132 Jefferson St., Baker, was pronounced dead at the scene. The woman was safely located shortly afterward.

Police said the woman was visibly shaken and had a sore neck but was otherwise uninjured, the Miami Herald reported. Police did not know why Dufore kidnapped his ex-wife.

The couple were divorced with four children, the release said.

The officer who shot Dufore is a 23-year veteran of the Police Department, the Miami Herald reported. The Florida Department of Law Enforcement, which declines comment on police shootings, is investigating the incident.
