Lopez said she asked whether he had a gun and he said no, so Bollinger allegedly offered to bring hers and said he could keep it to sell if he wanted, according to the affidavit. Joseph McDaniel Lopez, 22, said he responded to a Craigslist ad titled "I want to put a hit on myself", KMGH-TV reported.
Because he struggled with depression and suicide attempts, Lopez told police, he used "a fake persona of a hit man that he had created for himself", and said he talked to Bollinger using that persona to convince her he was a hit man and willing to help her commit suicide, the affidavit said.
Joseph Lopez (CBS Denver via CBS News) Lopez told investigators that when they arrived at the spot where Bollinger was shot, she "knelt down on the ground and that he knelt down along her left side and slightly in front of her", court records said.
According to the Adams County coroner, she was killed by a single gunshot wound to the head. He said Bollinger provided the gun, which he took along with her purse.
Lopez described her final moments, saying they both knelt, said a prayer and that he then got up, closed his eyes and fired.
Lopez told authorities that at no time did "they have or consume any type of drugs".
But after police pulled up Global Positioning System data from Lopez's phone that placed him where her body was found, he admitted he killed her with a single shot to the back of the head.
'Spot a gay' list in Malaysian newspaper sparks outrage
Just a few months later Sameera Krishnan, a 27-year-old trans woman, was then stabbed and shot three times at her florist shop. In March 2017, the release of Disney's Beauty and the Beast was postponed in Malaysia, because it contained "a gay moment".
Before Bollinger's death, suspicion of the murder fell on Shawn Schwartz, a man whom Bollinger had received a restraining order against in December, reported the Daily Camera.
Denver7 was the first to report the details in the affidavit, and since publishing the article Friday, many questions from Facebook users surrounding the alleged murder-for-hire plot remain unanswered - like how, if true, could someone go through with such a plan?
Friends and relatives told investigators that Bollinger had a history of suicidal thoughts, according to the affidavit.
He claims that she wanted to be shot and killed and that he tried to talk her out of it.
McIntosh was adamant at Friday's news conference that investigators may not have uncovered the true motive.
The victim's friends say she had a history of suicidal thoughts, but had applied for a job right before she was killed and did not communicate any intent to end her life.
"We believe that from what we now see, that we have the lone suspect in this case ...", McIntosh said. "This was murder", she wrote.
Lopez is being held without bail on murder charges. "If this is something that the victim was pursuing and asking for, it doesn't alleviate his legal responsibility, but it certainly mitigates it".
