BRIGHTON, Colo. (CBS4) – The Westminster man who allegedly confessed to killing a 19-year-old Pueblo woman who is missing and presumed dead faced a judge for the first time on Monday.

Police arrested Christopher Waide, 23, on Thursday night. On Monday morning in Adams County Court Waide learned he will not be formally charged until Friday. He faces first degree murder and sex assault charges.

Late last week Waide, who is being held in jail without bond, allegedly confessed to the brother and boyfriend of Lea Chali Porter that he murdered her.

Porter went missing earlier in June and police say the last person to see her was Waide. They said she was staying with Waide.

Porter hadn’t used her cellphone since June 3 and her social media accounts and credit cards hadn’t been active since then either. Her car was still in the parking lot of Waide’s Westminster apartment after she went missing but her personal belongings inside were gone.

Police have executed search warrants on Waide’s apartment and his car, and they say he is cooperating with police in their search for Porter’s body. A local trash company is also assisting police and part of a landfill has been cordoned off.

Porter’s stepfather Michael Jackson told CBS4 in the Adams County Courthouse he is very angry with Waide for the alleged murder.

“I want him to suffer. I want him (to get) life in prison in regular jail. And if they don’t do it I’m going kill him myself,” he said.

Waide’s family was also in court on Monday but they didn’t agree to any media interviews.

Porter’s family says they’ve read Facebook messages Porter and Waide. The messages allegedly show Porter rejecting romantic advancements that Waide made toward her prior to her visiting his Westminster apartment.

Porter’s family also claims that part of police evidence is a manifesto allegedly written by Waide.

“(It’s about) capturing a girl and sexually assaulting her and killing her and holding her prisoner,” Jackson said.

Westminster police told CBS4 they are working on their plan to find Porter’s body, but they aren’t revealing many details about their search.
