The day after that discussion, William Mussack vanished.
A woman has been charged with murder after her father's body was found encased in concrete in the crawl space under his home in a Denver suburb just one month after he suspected his daughter tried to poison his hamburger.
Jennings has been charged with first-degree murder after deliberation and tampering with a deceased human body.
The Federal Heights Police Department said Jennings and Mussack shared a house.
Days later, police made a second visit to the home, and that's when Jennings told them she had not seen her father for several weeks after he had left for the mountains with his girlfriend. Her admissions and cooperation would soon end, however.
Police returned on January 10 and began breaking up the concrete in the crawlspace, at which point Jennings stopped talking to them and requested a lawyer, according to the affidavit. "At this time, the interview was ended".
Authorities said the suspect attacked a woman in December in Compton and had also been linked to 11 other cases that were being investigated by both Los Angeles police and the Los Angeles County sheriff's department.
Police said Jennings told the officer that she would her uncle and let him know what was going on. When the victims are in his auto, the suspect then pulls out a gun, takes them to a remote area in South Los Angeles, sexually assaults them and releases them.
Later that day, officers returned to Mussack's home. Brian Mussack said that was the last time he heard from his father. Jennings showed the officers the basement, where her father slept, according to police. Family members and William Mussack's girlfriend all told investigators that the lack of communication was out of character for him, and that he always kept his cellphone with him.
According to the Gazette, Jennings told officers conducting the welfare check that her father did not live there.
His girlfriend told police that he had agreed to go to a party with her on December 9 but never showed up. When officers returned and got permission from Jennings to search the home, officers reported in the affidavit that the house smelled "like sewage and something rotting".
Police found "a bed covered in women's clothing".
The officer paid a third visit to the home on December 30, at which time Jennings refused to allow him inside.
Brian Mussack also told police officers that his sister sent him text messages claiming that that their father had been abusive toward her and that he couldn't afford to make his house payment. Mussack's son told police the same thing.
Forty-four-year-old Dayna Jennings was arrested last Wednesday, Jan. 10, for the death of her 69-year-old father William Mussack, according to FOX8. Three vehicles registered to Mussack were in the driveway. Mussack's family said he did not know anyone in Arizona.
If convicted as charged, Flowers faces a maximum possible punishment of life in state prison, as well as lifetime sex offender registration. The signature on this check did not match Mussack's, the representative told investigators.
Jennings' first husband, Joel Jennings, told police that his ex-wife "adored" her father, but that he believed she might have killed Mussack because it was not like his former father-in-law to disappear and not contact his family, the affidavit read.
Police said Jennings' most recent ex-husband described her as unstable and as having been in a "downward spiral".
