'Dog the Bounty Hunter' loses his wife.

Beth Chapman, wife of Duane "Dog the Bounty Hunter" Chapman, died Wednesday. She was 51.

Duane, 66, announced her passing on Twitter, writing, "It’s 5:32 in Hawaii, this is the time she would wake up to go hike Koko Head mountain. Only today, she hiked the stairway to heaven. We all love you, Beth. See you on the other side."

Beth was first diagnosed with stage 2 throat cancer in November 2017. She underwent successful surgery, but doctors months later told her the cancer had returned. Although she began chemotherapy in December 2018, Duane told Us Weekly at the time that she wanted to explore alternative therapies instead.

"Beth will not take anything the doctors want to give her. Even the doctor told me he doesn't want her to have seizures if the pain is that bad, but she won't do it," he said. "She takes over-the-counter pain meds. She will not take anything prescription."

Beth wrote on Instagram in February that she was testing out CBD and THC-based therapies and alleged that chemotherapy was "poison."

In April 2019 she was admitted to a hospital in Hawaii with "serious breathing issues," but recovered.

Then, this last weekend she was rushed again to the ER and placed in a medically induced coma. Sources told TMZ that Beth was having trouble breathing due to her throat cancer and described the incident as a "choking emergency." Her family, including daughter Bonnie, reportedly traveled to Hawaii to be by her side.
