COLORADO SPRINGS, Colo. (KXRM) — A haunting note written by a former United States Air Force Academy cadet has led her parents to file wrongful death claims against the academy.

“Do all that you can to make sure I am the last one,” was the chilling directive 22-year-old Cailin Foster left in her suicide note to her parents on Nov. 7, 2021.

At the time, her note seemed cryptic to her parents, Gary and Colleen Foster, who were largely unaware of what their daughter endured during her time as a cadet.

“We didn’t know she had thoughts of suicide ever. It never would have crossed our mind that she would ever have thought that at all. We had no idea,” expressed Colleen.

In the past two years, they found out about an alleged rape Cailin experienced during her freshman year in the fall of 2017 and the battles she faced with suicidal thoughts in the following years.

On Oct. 27, with heavy hearts and a determination for justice, the Fosters filed two wrongful death claims against the academy, seeking accountability and reformation within its walls. Their relentless pursuit stems from a belief that a timely intervention from the academy could have altered the tragic outcome.

“She should still be here today, and something could have been done earlier for her while she was at the academy. She should still be here,” lamented Colleen.

Cailin, a native of Colorado Springs and a graduate of Palmer Ridge High School, followed her father’s path of graduating from the academy with a degree in mechanical engineering. Her father recalls how proud he was to find out his daughter was carrying on his legacy.

“She could do pretty much anything she put her mind to. I always used to call her sunshine,” said Colleen, describing her as dynamic and vivacious.

After her freshman year, both parents noticed a change in Cailin’s personality as she went from a bubbly outgoing teen to a more reserved one. Colleen also recalls Cailin telling her that her hair had begun falling out and that she had gained over 30 pounds.

At the time, the Fosters attributed these changes to the stress and rigor of the academy. But looking back, they now think the stress was rooted elsewhere.

“I really think that rape caused her to have unbelievable trauma in her life. Her weight was changing, and I attribute that to all that stress and is also one of the reasons her hair started falling out,” said Colleen.

Cailin was two months into her first assignment in Dayton, Ohio when she took her own life.

Gary, a retired Air Force lieutenant colonel who graduated in 1990, attempted to engage with academy leadership about what happened to his daughter. He spoke with people who were his former colleagues and friends, only to be met with what he described as indifference.

When they requested a report regarding the investigation into their daughter’s death, the academy sent them 159 black pages of redacted content.

“Not one letter, word, or punctuation mark was provided. They literally gave us 159 pages like this,” said Gary in disbelief.

Through speaking with Cailin’s friends and the El Paso County Sheriff’s Office, who investigated her death, the Fosters said their quest for answers revealed a chain of negligence. They say Cailin reported her alleged rape to another cadet above her in the chain of command, along with both of her roommates, who also reported rapes they endured in separate instances.

According to the El Paso County Sheriff’s Office investigation, the man accused of raping Cailin was written a no-contact order a few months after the alleged rape in March 2018. The 48-page investigation also revealed the man disenrolled due to poor academics and was honorably discharged.

“They gave him an honorable discharge. That is a slap in the face to every military member that honorably served,” said Gary.

They also found out that academy leaders were notified that Cailin was having thoughts of suicide but decided to let her schedule her own mental health appointment. She was, however, placed on an at-risk list but then subsequently removed before graduation, which means it wasn’t on record while she was on her first assignment.

“When I was at the academy, I ran the cadet at-risk list, so I knew what the proper procedures were. When I asked for where’s the placement and removal letters, they did not provide them. I mean, something as simple as that. They just will not provide,” said Gary.

Gary worked at the academy 20 years ago when they issued the “Agenda for Change” report in 2003 after facing widespread criticism and charges of ongoing sexual misconduct. The report detailed 43 weak points in need of correction.

“There’s a saying, ‘If we don’t learn from history, we’re going to repeat it,’ and sadly, 20 years we’re back, and it just took my daughter’s life. They knew that Cailin was suffering. They failed her as a freshman, and they failed her all through her junior and sophomore years with her roommates all the way up to her senior year,” said Gary.

According to a report by the Department of Justice released in March 2023, incidents of sexual assault at U.S. military service academies were at the highest rate on record in the 2021-2022 academic year.

The report states, “While all three Military Service Academies saw an increase in prevalence among men and women as compared to 2018, the highest rates were evident among women at the United States Naval Academy and United States Air Force Academy.”

Driven by Cailin’s final plea, the Fosters are now resolute in their mission to make sure she is “the last one.”

“The last one to be raped, the last one to take their life, the last one to not receive the care that is really needed. We care about every single one of those cadets up at the Air Force Academy, they all deserve to have a great future. None of them deserve to have any harm come their way,” said Colleen.

Their claims seek both monetary damages and systemic change within the academy. Amidst numerous advocacy efforts, their fight encompasses destigmatizing mental health for the military, empowering cadets to report sexual assault, and ensuring that the chain of command safeguards victims of such assaults.

The Fosters filed an appeal requesting the 159-page report unredacted. As of Nov. 14, the academy said they are “unable to meet the time limits imposed by the FOIA,” and their request will be delayed until Dec. 13.

FOX21 reached out to the Air Force Academy earlier this week but has not received a response. As of 7:00 p.m. on Tuesday, Nov. 14, a spokesperson with the academy says he is “hopeful we’ll have an answer by mid to late afternoon tomorrow.”

If and when they send a response, FOX21 will update this article as soon as it is received.
