An armed man's bid to rob a taxi driver ended Sunday when he was fatally shot by authorities near a tunnel to Canada. The gunman had shot a motorist during an ill-fated carjacking.
Police did not immediately release the name of the gunman.
Earlier in the evening, police thought the man had opened fire at the Windsor Tunnel's entrance.
Police said gunman tried to commandeer a vehicle and shot the driver.
That motorist -- Anthony Saura, 63, of St. Clair Shores, a Detroit suburb -- was treated at a local hospital and released.
Federal officers and Detroit police fatally shot the gunman on the U.S. side of the tunnel linking downtown Detroit to Canada.
After the unidentified taxi driver picked up the suspect and was ordered to turn over his money, the cabbie drove to the tunnel seeking help, Police Lt. Bill Rice said.
Near the tunnel's entrance, the man jumped from the taxi and tried to carjack a Cadillac driven by Saura. After shooting Saura, the gunman fired several rounds at federal officers and Detroit police, who shot the man, Rice said.
