Friday he jumped at least 50 feet at a construction site in Aurora.
The teen is a student at Eaglecrest High School.
It's the same school where was less than a week ago a second student committed suicide.
The Cherry Creek School District says neither incident is because of bullying.
Those who work with teens and families say things that may seem minor to an adult can have a big impact on teenagers and even pre-teens.
The signs can be hard to spot, and experts say the best thing for parents to do is just talk.
The school district says the two didn't know each other and one of them had only been a student at Eaglecrest for five weeks.
Dr. Larry Curry is a child and family therapist. He says even if the two hadn't met, news travels fast.
"[One person's] reason for doing it may be entirely different than why someone else did it, but it just seems like an easy way out," he said.
Curry says the most important thing to do is speak openly and honestly with your child.
"We think if we get an 'OK' answer everything is alright," he said. "We're not willing to probe too far because we're afraid we may uncover something. That's what we need to look for. We need to really make sure everything is OK."
Avoiding the subject altogether could be the worst thing to do, according to Curry.
"There is a certain amount of shame and guilt that goes with whenever a young person hurts themselves," he said. "But the reality is when we don't talk about it we're also causing harm and hurt and we're setting up a bad situation for someone who may be experiencing the exact same symptoms."
Curry says the rates of teen suicide around the nation are actually down in the last decade slightly, but because more and more people are talking about it, teen suicide seems more prevalent. Curry says make no mistake, the rates are still too high.
Eaglecrest High School has posted a guide for parents about how to talk to their teen about suicide on the school's website.
