The balloon crashed into a power line around Central Avenue and Unser Boulevard, causing power to go out in the area, Albuquerque Police Department (APD) confirmed on Twitter.

A fifth person was critically injured and hospitalized, but succumbed to his injuries, police said. Of the five people that were killed, three were men and two were women, Albuquerque Police confirmed in a statement.

“Liz and I are heartbroken by the ballooning accident this morning,” Albuquerque Mayor Tim Keller tweeted. “This is a terrible tragedy for our city and the ballooning community worldwide.”

Police are not publicly naming the victims at this time, but Gallegos said the deceased are between 40 and 60 years old, adding that police believe the hot-air balloon pilot to be among the dead.

Power has been fully restored to affected customers in the area of the incident, Public Service Company of New Mexico (PNM) spokesperson Shannon Jackson told CNN.

“Everyone at PNM is deeply saddened by this tragic loss,” Jackson said. “We are thinking about the family and friends affected by today’s events. We will continue to do everything we can to support first responders in this evolving situation.”

PNM was not able to re-energize the transmission line affected by the crash or restore power until the investigation was complete, Jackson said.

Albuquerque Fire and the New Mexico State Police are on the scene, and the Federal Aviation Administration (FAA) and the National Transportation Safety Board (NTSB) will investigate what caused the hot-air balloon to crash, according to police.
