I'm Adrienne Canning, and this is a story that literally took me high up into the Rocky Mountains.

I wanted to see for myself where this all happened, so I was harnessed to a tree in the very same spot where the mother and doctor fell to her death.

It was absolutely terrifying, and I can only imagine the fear she felt in those final moments.

Her death opened up a lot of questions about her husband, not just from their marriage, but his first one, too.

I knew this would be a tough case to prove. Here's over the edge.

My name's Annakate, and I'm nine years old. I'm in fourth grade.

Annakate once had an aunt named Tony. They lived a few states apart, but were never more than a phone call or a letter away.

Dear Aunt Tony, how are you? I have no homework. We finished a little pair, eight days, till Christmas. I'm so excited. I love you. Annakate.

She still writes her letters, even though Tony can no longer respond.

Dear Aunt Tony, are you enjoying it in heaven? I miss you very much. I read a book about heaven. It must be great.

Love your niece, Annakate.

Annakate was seven when her aunt died. It was sudden, scary, and heartbreaking.

So she took out an old shoebox, decorated it, and filled it with thoughts of Aunt Tony.

Now she's dead. Now we can't see her again, and our lives will never be the same again.

The ripple effect of Tony's death was huge. She was a respected doctor, an ophthalmologist who had a thriving practice first in Jackson, Mississippi, and later in Denver, Colorado.

A devout Christian who sang in her church choir, a mother to a little girl named Haley, a wife to a man named Harold, and the older sister to Annakate's dad, Todd Bertolay.

This story is about Tony and what happened to her one bright sunny day, high up in the mountains.

Hey, my mom. What's your dress? You look great. I did an out-brained mouth rescue game, immediately.

It's also about how secrets long buried sometimes don't stay that way.

Where did Tony fit into your family?

She was the middle between two brothers. Sometimes she thought that was an advantage, and sometimes she thought it was a disadvantage.

Being the only girl with two brothers. Obviously, we're not going to sit down and play barbies with her.
