"It is a true mystery as to what did happen to her and where she's at. In this case, we don't have a crime scene, so we don't have her body to tell us what did happen to her," Bo Roberts, with the Lubbock Metropolitan Special Crimes Unit, said.
A 30-year-old mother living outside Lubbock County, Maegan Hembree was last seen Feb. 26, 2013, and there has been no trace of her since.
"She was a singer, she was a beautiful singer. She's very bubbly, She in working with people and talking to people, she was very kind and very thoughtful. She was just a very well liked person. She got along with anybody. She loved her son more than anything. He was five years old when she went missing," Maegan's father Jerry said.
Jerry Hembree said Maegan left Hobbs around 4 p.m. to start a new life in Lubbock.
It was his last kiss goodbye.
"I told her I loved her, kissed her on the top of the head and told her I loved her and she left out," Jerry said.
At roughly 7 p.m., Investigator Bo Roberts said she made a stop that changed everything.
"It became pretty apparent early on in the case who the primary suspect was and that was the guy that she went to see briefly before she was going to meet with friends," Roberts said.
Michael Ramsey is the primary suspect.
He is from Grand Seline, Texas, and he came to Lubbock through a halfway house.
Detective Roberts said Ramsey knew Maegan for about six weeks before her disappearance.
"He's very well versed in criminal offenses. He numerous trips to the penitentiary prior to this incident. Michael Ramsey is now serving an 80 year sentence in the penitentiary for crimes he committed in Van Zandt County," Roberts said.
It all became very real to Jerry when Robbie, Maegan's mother, faxed him the missing person's flyer.
"When it came over the fax, and it was a colored fax, and it came over the fax and it showed the missing persons and it showed Lubbock County Sheriff's Department and it showed all the seriousness of it, I absolutely lost it. I just wailed. I wailed. I cried and wailed. It wasn't a good sign. It wasn't good," Jerry said.
The biggest hurdle in this case: There is little to no physical evidence.
Cell phone records show consistencies in Ramsey and Hembree's locations on the day she disappeared, and Ramsey continued to use her car after, but there is not enough evidence against him to charge or prosecute.
"He is the only one who holds the key to any further information unless someone has information that would lead us to a different suspect or a different outcome," Roberts said.
Roberts and the Lubbock Metropolitan Special Crimes Unit said they will continue to work this case to eventually bring resolution to Maegan's family.
"Bo Roberts has not stood down once and he has gone all the way and he continues and he's kept a couple promises and he's made a few promises and so far I wouldn't want anyone else on the case. He's going to see us through on this," Jerry said.
It has been almost six years since Maegan's disappearance, but Jerry is remaining hopeful.
"I believe that there's still someone that knows something and if there is, we need all the information that we can so that we can bring Maegan home," Jerry said.
