WASHINGTON - The family of a missing D.C. woman is speaking out Monday night about the ex-boyfriend police have questioned during their investigation.

After 10 days, the family of 47-year-old Pamela Butler is losing hope they will ever see her alive again. They say they believe Butler's ex-boyfriend is the key to solving the mystery of her disappearance.

Off camera, the family watched ABC 7/NewsChannel 8's entire 40-minute interview with Butler's 43-year-old ex-boyfriend who has acknowledged he may be the focus of the police investigation.

"They're searching my car they got stuff from my house and they're going to find that there's nothing showing that I did anything to her," the ex-boyfriend said. "If they had any direct link of me with her disappearance or doing something to her I wouldn't be sitting here right now."

Butler's brother Derrick Butler comforted his 76-year-old mother Thelma Butler after watching ABC 7/NewsChannel 8's interview with her daughter's ex-boyfriend. The couple broke up about 24 hours before Butler's last known contact with anyone.

"As a mother I feel that there is something you are not telling us, just let it out," Thelma Butler said.

Butler's ex-boyfriend did say he wants Butler found and he knows the family's pain, but after voluntarily going into police questioning twice, he said he's not going to cooperate anymore without a lawyer.

He said police trashed his place while searching for evidence with a warrant and that his car is in police custody. He also said he told police he had a dream he was jogging with Butler in Seneca Creek State Park. That led to a search of the area in Montgomery County (web | news) .

He also said he would not take a lie detector test because, he said, it is unreliable.

"Why don't you take my blood that is an exact science there's no mistake about blood. You find my blood somewhere where it shouldn't be or her blood somewhere it shouldn't be, there's no mistake on that," he said.

The ex-boyfriend said he understands why police are taking such a hard look at him because of the break up and because he was seen coming and going from the house on Butler's home surveillance video in the days after she disappeared.

He said the Friday before Valentine's Day, Butler broke up with him because he wouldn't sever ties with the child of a former girlfriend.

"I loved her you know our relationship ended in a way that I didn't expect and it was hurtful but I walked away from it," he said.

He said he was picking up and dropping off property, but Butler was never seen again. "I didn't do anything to her you know like I told the police you seen the video and she did not leave with me," he said.

Meanwhile, Butler's mother believes the ex-boyfriend can help solve the case. "Come out and tell us as a mother... please just come out," Thelma Butler pleaded.

ABC 7/NewsChannel 8 has now learned from Butler's family that the ex-boyfriend told them he would be willing to take a polygraph test. He could not be reached for confirmation Monday night because his cell phone is in police custody as evidence.
