MADISON COUNTY, Miss. (AP) -- Members of the AirCare flight crew involved in Monday's helicopter crash in Madison County, Mississippi have been identified.

Dustin Pope, 35, of Philadelphia was the base supervisor for AirCare in Columbus and a flight nurse, and Jakob Kindt, 37, was a critical care paramedic from Tupelo. They both started working for UMMC on Aug. 14, 2017. The Med-Trans pilot was Cal Wesolowski, 62, of Starkville.

The helicopter was returning to Columbus from a patient transport when it crashed in Madison County at around 12:30 pm, killing everyone on board, the University of Mississippi Medical Center's vice chancellor for health affairs, Dr. LouAnn Woodward, said at a press conference.

"The entire Medical Center family is heartbroken over this," Woodward said.

This was the first crash in the 29 years that the AirCare emergency services have been operational, according to a statement from the university. The school did not offer a reason for the crash but said that the Federal Aviation Administration and other authorities were investigating.

AirCare transport services have been temporarily grounded, and the Medical Center is working with health care and medical transportation services around the state to meet the needs of Mississippians.

UMMC is offering support to the team members and families affected by this loss and will continue to support the AirCare and Mississippi Center for Emergency Services teams and Medical Center employees in any way possible.

"It's a tragic reminder of the risks Mississippi's first responders take every day to keep us safe," Mississippi Gov. Tate Reeves said on Facebook. "Our state will never forget the sacrifice of these heroes."
