DENVER -- A man accused of shooting and killing a 19 year-old Broomfield woman may avoid spending the rest of his life behind bars after agreeing to a plea deal.

Natalie Bollinger was shot execution style in December of 2017 after allegedly posting on Craigslist that she wanted to "place a hit" on herself.

Her alleged killer, 22 year-old Joseph Lopez, was arrested in the days following the murder and allegedly confessed to police that he met Lopez after answering the post on Craigslist.

However, Bollinger's family says they have been informed Lopez will plead guilty to 2nd degree murder as part of a plea deal, agreeing to a 50-year prison sentence with the possibility of early release for good behavior.

"We said no and they still offered it to him today. Our family does not agree with this or is willing to do any plea bargain. I'm dumbfounded. I'm so disappointed in the legal system in Adams County," said Ted Bollinger, Natalie's father.

The 17th Judicial District Attorney's Office declined comment because this is still an active case, but Ted Bollinger says prosecutors told him they're concerned a jury could be convinced Natalie's death was assisted suicide, not cold-blooded murder.

"This monster took my baby. There's no justice in this. He should die not as an old man. He should die now. He should die soon for this," said Bollinger.

"I need a super lawyer. They`re out there. I need someone that can take on Adams County, the judicial system, and fight for our family," Bollinger said.

Natalie Bollinger was killed in December 2017.

She was reported missing from Broomfield. Her body was discovered in a wooded area along Riverdale Road near McIntosh Dairy in Adams County December 29.

Joseph Michael Lopez, 22, was arrested in connection with the case in February.

Lopez told investigators that sometime after Christmas, he came upon an ad on Craigslist titled “I want to put a hit on myself" while looking at the “Woman seeking Men" category, according to an arrest affidavit.

Lopez claims the ad was posted by Bollinger.

A judge in Adams County has scheduled a hearing for Dec. 3 where Lopez is expected to accept a plead deal.
