COEYMANS, N.Y. - The escape of a small herd of buffalo from a farm is ending badly, with the animals being shot after crossing the New York State Thruway.

Three men believed to be associated with the farm shot three buffaloes Friday afternoon in a stream in woods in the town of Coeymans, about 10 miles south of the capital.

More shots were heard.

About 15 of the animals escaped Thursday from a farm across the Hudson River in the Rensselaer County town of Schodack. The owner believes they swam across the river to the town of Bethlehem, where they wandered across a busy stretch of Interstate 87 and into neighboring Coeymans.

Drivers slowed to avoid them.

Authorities have been warning that the loose animals are dangerous.
