Until we can find a name for ex BF these are the things that caught my eye about R. Stilgenbauer:
He was the last person to see and the last person to speak with Krista on 11 NOV (5:30 PM?). Her father has said in articles that he had called the evening of the 11th and it went to voicemail.
"Lueth was last seen by her friend Rick Stilgenbauer, who has subleased the apartment below her for the past five months. She recently broke up with her boyfriend, who had lived with her. He moved out of the apartment they shared between Nov. 6 and 11, Stilgenbauer said... Lueth and Stilgenbauer talked in his kitchen Nov. 11 between 5:30 and 6 p.m., after Lueth returned from class at MSU. She was concerned because her ex-boyfriend moved out and her rent would increase. She was planning to sell her truck and start working as a waitress to pay her bills, Stilgenbauer said... After Lueth left his apartment, Stilgenbauer did not hear anything from her upstairs apartment."
From what I gathered, her father said she had a class at 6:30 PM 11 NOV and never showed up? Her father said in an article that he assumed she left the house between 6:10 and 6:30.(he said he had tried to figure out her class schedule).
Professor at MSU says she didn't show up for class 12 NOV.
Father says he also called on 12 NOV, 13 NOV but went straight to voicemail. RS claims he tried to call her 12 NOV.
R.S (Stilgenbauer) subleased the apt. below hers for the past five months. Apparently she rented this house and sublet to him. (However, it was reported she knew him for eight years).
"On Nov. 13, Krista Lueth's friend visited the house Krista, 34, rented and found nothing out of place. She didn't, however, find Krista." R.S is also reported to have entered the apartment with two friends (did he have a key?, did female friend have a key? then again did she change the locks after ex moved out?)
I did not do all this research the wonderful sleuthers at:

did all of this research on articles. All I did was just read and extract items of interest that caught my eye. Kudos to them.
