HUTCHINSON, Kan. (KAKE) - The Reno County Sheriff's Office says a man and woman were killed in a motorcycle crash southwest of Hutchinson on Memorial Day.

Deputies along with fire department and EMS personnel responded at around 9:30 p.m. Monday to an injury accident at K-61 and Herren Road. The sheriff's office said the first arriving deputy found the woman and the second deputy found the man. Both died at the scene. 

The preliminary investigation shows the two were on a 2007 Harley-Davidson that was southbound on K-61. The motorcycle left the roadway and struck a highway sign, ejecting both of the occupants. 

"The driver and passenger were not wearing helmets at the time of the accident," the sheriff's office said in a release. "The investigation is still on going and speed is believed to be a contributing factor."

No names were released. 

Anyone who witnessed the accident or has information is asked to contact the sheriff's office.
