"We're still in shock...He had a heart of gold," said Misty Deupree.
31-year-old Beau was last seen January 24, leaving the Bordertown Casino near Seneca, Missouri.
On Tuesday, exactly seven weeks later from the date he disappeared, his sister Misty received the phone call she had been dreading.
"I knew when he was asking me if I was at home, I knew it wasn't good."
Misty says her brother's body was found by a farmer in Oklahoma along a tree line near County Road 130, west of State Highway 10.
The location where he was found was only half-a-mile away from his friend's house and two miles away from where the search party looked on February 16.
"We had missed him by two miles, and that's frustrating."
According to Misty, the detectives do not think foul play was involved. They say Beau looked as if he lay down to go to sleep and never woke up.
"It doesn't matter how prepared you are for this kind of outcome, because you can never fully prepare yourself."
In dealing with this tragedy, Misty says the love and support from family and friends is helping, and even though Beau is gone, she will forever cherish her memories.
"If you needed help, he would help. He would give his shirt off of his back...It didn't matter what kind of person you were, he would befriend you immediately, you were drawn to him."
Misty says the medical examiner's office is doing an autopsy and a toxicology report and she hopes with those results she will find out exactly what happened to her brother.
