While mountain biking with several riders from a local cyclist group Sunday, April 1, 71-year-old David Mangan of Prescott collapsed and died, according to a Yavapai County Sheriff’s Office news release.

The incident occurred on the West Side Story Trail, located off a forest road south of Iron Springs Road and east of Highland Pines in Prescott, at about 1:30 p.m.

Prescott Fire Department and the Central Arizona Fire and Medical Authority were the first to respond.

They were able to find Mangan’s exact location by pinging the 911 caller’s cell phone, giving them GPS coordinates, said Prescott Fire Department Battalion Chief Scott Luedeman.

However, since the emergency was along a trail system, it took responders about 35 minutes to reach Mangan, Luedeman said.

When they arrived, an off-duty nurse riding with the group had already started CPR, according to the news release.

Fire department personnel took over, but were unable to save Mangan. A prior medical condition may have contributed to Mangan’s death, the release stated.

One of the cyclist group members told deputies Mangan met the group about 1 p.m. and he appeared OK. The group left the trail head about 1:10 p.m. and took a break around 1:30 p.m. About 5 minutes later Mangan collapsed.

With warmer weather, Luedeman said that before going out on the trails, the following precautions should be taken:

• Carry a charged cell phone

• Dress appropriately for the day’s weather

• Bring plenty of water and food for the day’s activities

• Let someone know where you will be going

• Keep track of your location regularly as you progress on your adventure. In the event you have an emergency, your exact location can help emergency crews reach you in the fastest way possible.
