The last time I heard my daughter’s voice, she was laughing so hard she could barely speak.

She said, ‘Mom, David just put sunscreen on his nose like a clown.’

I could hear him in the background, chuckling deep and warm.

That sound is printed on my heart forever.

My name is Carol Mitchell, and I live in Boulder, Colorado.

My daughter Emily was thirty-one years old and six months pregnant.

After two heartbreaking miscarriages, this baby was our miracle.

She and her husband David had been married for four years.

They were high school sweethearts, the kind of love that made you believe in good things.

David was a construction manager.

He was steady, polite, and he called me ma’am every single time.

Emily worked as a pediatric nurse.

She had the most tender hands and the softest heart.

When she told me she was pregnant, she cried on my front porch.

She whispered, ‘Mom, this one is going to make it. I just know it.’

I held her for a long time and said, ‘Yes, sweetheart. This one is going to make it.’

In early March of 2012, Emily called me with excitement.

She said, ‘David wants to take one last trip before the baby comes.’

I asked, ‘Where to?’

She laughed and said, ‘The Sonoran Desert. Down in Arizona. I have always wanted to see it before I become a mother.’

I told her to be careful and to drink plenty of water.

She promised she would call me every single day.

And for the first few days, she did.

The calls were full of wonder.

She said the desert sky looked like a painting that stretched on forever.

She said the quiet was so deep she could hear her own heartbeat.

She told me the baby kicked every time the sun went down.

David would get on the phone and say, ‘Carol, your daughter is eating jalapeno chips and pickles together.’

Then Emily would laugh and say, ‘Don’t listen to him, Mom. I only had one.’

Those calls were pure sunshine.

But on March 14, 2012, everything changed.

Emily called me at 6:42 in the evening.

Her voice was soft and full of peace.

She said, ‘Mom, I just wanted to hear your voice before we settle in for the night.’

I asked how they were doing.

She said, ‘We found the most beautiful spot. The saguaros are everywhere. David set up the tent right next to a dry wash.’

I felt a small shiver, but I pushed it away.

I said, ‘That sounds lovely, sweetheart.’

She said, ‘I will send you a photo in a little while.’

Then David took the phone.

He said, ‘Carol, I promise I will take care of her. We will be home in two days. Save us some of that lemon cake.’

I told him, ‘You just bring my girl back safe, David. That is all I ask.’

He said, ‘Yes, ma’am. You have my word.’

I waited for the photo.

At 7:04 that night, my phone lit up.

It was a picture of Emily and David sitting inside their tent.

David had one arm around her, and he was grinning from ear to ear.

Emily was laughing at something just off to the side.

Her hands were wrapped around her round belly.

She looked so happy, so full of life.

I sent back a message that said, ‘My heart is full. Be safe. I love you both.’

She replied with three simple words.

‘Love you too.’

Those were the last words I ever received from my daughter.

The next morning, I waited for her daily call.

It never came.

At first, I told myself the service was bad in the desert.

I thought maybe they were hiking and wouldn’t have a signal for a while.

By noon, I was pacing my kitchen floor.

I called her phone.

It rang and rang and then went to voicemail.

I called again.

Same thing.

By 6:00 that evening, my hands were shaking.

I called David’s phone.

It went straight to voicemail.

My stomach dropped like a stone.

I called the hotel where they had stayed before heading into the desert.

A polite young man told me they had checked out two days earlier.

He said they had been smiling and excited.

He said they had asked for directions to a remote trailhead.

I hung up and called my son, Robert.

I said, ‘Robert, something is wrong. I cannot reach your sister.’

He drove over immediately.

We contacted the local sheriff’s office.

Then we called the Pima County Sheriff’s Department in Arizona.

A deputy named Sergeant Tom Barrett took our report.

He asked for their vehicle information, their camping gear, and their last known location.

He told us they would start a search right away.

That night, I did not sleep at all.

I sat in my recliner and clutched my phone like a lifeline.

I replayed Emily’s last voicemail over and over again.

Her voice filled my dark living room.

She said, ‘Mom, I love you. The sunset is the most beautiful thing I have ever seen. We will call you tomorrow.’

I must have listened to that message a hundred times.

By sunrise, I knew in my bones that my daughter was not coming home.

The search was massive.

Helicopters flew over the Sonoran Desert for days.

Search dogs covered miles of rocky ground.

Volunteers on horseback combed the washes and ridges.

They found no sign of Emily or David.

No footprints.

No campfire.

No tent.

No car.

It was as if the desert had swallowed them whole.

Sergeant Barrett called me every evening for the first week.

He was kind and honest.

He said, ‘Mrs. Mitchell, we are doing everything we can. But this is some of the most unforgiving terrain in the country.’

I asked him, ‘Do you believe they are still alive?’

There was a long pause.

Then he said, ‘I believe in miracles, ma’am. I really do.’

But I heard the doubt in his voice.

And it broke me.

The search went on for three weeks.

Then it was scaled back.
