A Phoenix-based flight attendant is one of two people who died over the weekend following a seemingly unprovoked stabbing spree in downtown Denver.

Celinda Levno, 71, is being remembered by loved ones and members within her industry for a career that spanned decades serving flight passengers. Efforts are underway to fund a funeral for Levno.

Authorities have arrested a man as a murder suspect in the fatal attacks that left two survivors as the investigation continues. Here is everything we know about the attacks and the Arizona woman who lost her life.

How did the stabbing unfold?

A woman died Saturday in a stabbing attack near 16th Street Mall, a shopping center in downtown Denver, according to Denver police. There were also three men assaulted, leading to the deaths of two. The first three stabbings took place Saturday, while the fourth stabbing, which was also fatal, happened Sunday.

The fourth stabbing victim was pronounced dead at a hospital, while the surviving stabbing victims suffered serious injuries or injuries that were not life-threatening.  

Who is the suspect?

Elijah Caudill, 24, is charged on suspicion of two counts of first-degree murder and two counts of attempted first-degree murder in connection with the four stabbings and was jailed as of Monday, police said. The area of 16th and Wynkoop streets was searched by police, who found Caudill with a knife and matching the suspect’s description, the Denver Police Department said.

Police said the attack appeared to be random. A potential motive was being investigated, police added.

The suspect was described by Denver Mayor Mike Johnston as a Colorado-born white male with a criminal history who was released from jail in November 2024. 

Who was Levno?

The woman killed in the stabbing was Levno, an American Airlines flight attendant, according to an Association of Professional Flight Attendants spokesperson on Tuesday. Levno, who was on a layover in Denver, started more than three decades ago at America West before its merger with American Airlines, the APFA said.

American Airlines confirmed Levno’s death was a result of a “senseless crime,” offering condolences and assuring its cooperation with law enforcement in the investigation.

A GoFundMe page was created by Jessica Dale, a friend of Levno, to help pay for funeral expenses.

Levno is survived by her husband, John, and her sister, Melanie, according to the GoFundMe page. Her Facebook page reveals she was a concert flutist, and the GoFundMe page mentioned she was deeply involved in the Arabian horse industry.

“She will now be with us every stride, and her love for horses will be carried on through all of us,” Dale told The Arizona Republic in a statement. 

‘Senseless crime’: Phoenix-based flight attendant died during Denver layover

Following the conclusion of the 2024 season, the Denver Broncos signed 13 members of their practice squad to reserve/future contracts.

Four other veteran members of the practice squad were not given new deals ahead of the 2025 offseason. The Broncos are not re-signing wide receivers Michael Bandy or David Sills, tight end Donald Parham or offenisve tackle Cam Fleming, at least not at the moment.

Parham is perhaps the most intriguing player not re-signed. The 6-8 tight end with 11 career touchdowns spent the entire season on Denver’s practice squad.

Players that are not on an active roster at the end of the season are eligible to sign reserve/future deals. After signing reserve contracts, players officially join the 90-man offseason roster when the new league year begins in March.
