Dr. Phil shares four traits that people who commit suicide have in common.

1. They believe that people in their lives are better off without them; they think they’re a burden.
2. They begin to exhibit high-risk behaviors. They’re not afraid of dying because they’ve made the decision.
3. Oftentimes, you see a real upswing in their attitude and demeanor because they’ve made the decision and they're short-termers, so they’ve got a plan to escape their suffering. You see a lift in mood because they’ve got their ticket out.
4. You see an absence of forward thinking with people who are going to kill themselves. They don’t make reference to next week, next month, next year, because they are not going to be there, and they know that.

“There are just different things that you see sometimes with depressed people,” he says to the parents of Amber Hilberling who died in prison in what the Medical Examiner is calling a suicide.

Hilberling was serving a 25-year sentence after being convicted of second degree murder in the death of her husband, Josh, who plunged to his death after police say a push from Hilberling during an argument caused him to fall through a window of their 25th-floor apartment in Tulsa, Oklahoma in 2011. Hilberling was found hanging in her cell on October 24, 2016, leaving behind her 5-year-old son, Levi.
