Four people died and one person was in critical condition after a hot air balloon crash over the weekend in Eloy, Arizona, authorities said.

There were 13 people on board the balloon at the time of Sunday's crash, the Eloy Police Department said in an updated statement on Monday. "This included eight skydivers, four passengers, and the pilot," police wrote. "It is important to clarify that the skydiving was intentional and was successfully completed by all skydivers before any issues with the hot air balloon were evident."

"That's when something catastrophic happened and the balloon crashed to the ground," police said, per Fox affiliate KSAZ.

According to ABC affiliate KNXV, witnesses said that the balloon went up and down prior to making impact.

Police have identified the four victims who died as Chayton Wiescholek, 28, of Union City, Michigan; Kaitlynn Bartrom, 28, of Andrews, Indiana; Atahan Kiliccote, 24, of Cupertino, California; and the pilot, Cornelius Van Der Walt, 37, of Eloy, Arizona.

As of Monday, Valerie Stutterheim, 23, of Scottsdale, Arizona, was listed as being in critical condition, police said.
