TULSA, OK -- Nearly three months ago, a young wife and mother hitchhiked to Tulsa, only to be brutally murdered and stuffed into a trash bag.

Tulsa Police detectives are still working to solve the case and have released never before seen video of the victim days and even hours before she was killed.

Lisa Bollaert hitchhiked from New York state to Tulsa with nothing but the clothes on her back, not even a cell phone.

She checked into the Salvation Army shelter April 27th and 28th, then moved to a Sand Springs women's shelter on the 29th.

On April 30th, surveillance video shot outside Tulsa's FBI office shows Lisa and a man who had given her a ride. She wanted to see if the FBI had any information on her before she went to an Army recruiting office to re-enlist.

"She was having some mental health issues. There's no crime against that, but some of her actions were a little bit out of the ordinary," said Sgt. Mike Huff, Tulsa Police Major Crimes Unit.

Tulsa Police believe the same man drove her to the military recruiting office.

Detectives would like to know who he is and talk to him, to better trace her next steps.

Police know she walked away from the women's shelter May 5th and video from a convenience store is the last record of her being alive, other than someone who saw her walking on West Charles Page Boulevard.

Her body was found the next day, dumped in the front yard of a rental house at 79th and South Elwood.

Someone saw a white man with brown hair in his 40's or 50's, driving a white, beat-up ‘70s truck similar to one near the time the body was dumped. 

Tulsa Police say extreme rage was exhibited in the murder.

"We're not jumping out and saying this guy's a possible serial killer, but the way some things happened makes us think he may have some characteristics of somebody who's either done this before and possibly, if we don't catch him, will do it again," said Sgt. Mike Huff.

Less than a month after Bollaert was seen walking on West Charles Page Boulevard, a man tried to force another woman who was walking there, into his car.

That man was driving a late ‘80s four-door Toyota, possibly a Tercel, that was red with a white top. He was also a white guy, possibly in his 50's with brown hair.

Police want to question him and are asking for help finding any more leads in the case.
