Officials say Edmond runner's death due to heart condition

(Edmond-AP) -- An Illinios medical examiner said today that an Edmond man died during a Chicago marathon from a heart condition.

The Cook County medical examiner determined that Dan Towns suffered from coronary atherosclerosis, a buildup of fatty tissues and calcium on the walls of arteries.

The 45-year-old collapsed around yesterday after finishing more than 22 miles of the 26-point-two-mile LaSalle Bank Chicago Marathon.

Towns worked as a geologist with Louis Dreyfus Natural Gas Company.

Ernie Knirk is vice president of exploration for the company.

Knirk said Towns competed in various marathons and had been looking forward to the Chicago marathon for more than a year.

Towns is survived by a wife, Debbie, and three children.
