JEFFERSON COUNTY, Wis. (CBS 58) -- One person is dead following a chain-reaction crash in Watertown.

Authorities were called to the area of Highway 26 just south of High Road for a report of a two-vehicle crash.

It happened around 11:33 a.m. on Wednesday.

While deputies were responding, a third vehicle crashed which caused one of the vehicles to burst into flames.

The investigation revealed that a vehicle was traveling northbound when it collided into the rear of a semi-tanker which was also northbound. The driver of the first vehicle sustained non-life threatening injuries.

A second vehicle then struck the first vehicle. The first vehicle then spun, striking the driver who was standing outside of the vehicle at that time. The vehicle then burst into flames. The passenger who had remained inside was pronounced dead at the scene. 

Names are being withheld pending family notification.

The investigation remains ongoing.
