(AP) — No criminal charges will be filed after a Kansas woman fell to her death from a party bus.

The family of 26-year-old Jamie Frecks responded Tuesday in a statement released through their attorneys.

The statement said the family appreciated the investigative work of the Wyandotte County district attorney’s office and understood the burdens of pursuing criminal charges. The family also is pursing civil litigation, and said in the statement that they hope to learn more as discovery continues.

Frecks died while celebrating a friend’s bachelorette party May 4 when she fell out of the 1999 wheelchair van-turned-party bus. She fell when the bus’ side double doors suddenly opened on Interstate 35 in Kansas City, Kan., and she was hit by several vehicles.
