(La Porte County, IN) - A Michigan City man was killed when he drove into the back end of a semi-truck on a motorcycle yesterday afternoon.

Timothy Hefner, 29, was pronounced dead at the scene, according to La Porte County Police.

Police said the investigation shows the 2006 Kawasaki was traveling recklessly and at a high rate of speed when it rear-ended the flat-bed trailer on a semi-truck on U.S. 20 near 400 West.

The truck driver, Daniel Smith, 46, of Toledo, Ohio, told investigators he decreased his speed to 40 miles per hour as he approached the area of the Renaissance Academy Montessori Center. He then felt something collide with the rear of the trailer and stopped to investigate.

Police said the results of a toxicology test on the victim were still pending.
