"This just came out of nowhere," said Nancy Lanham, Kari Baker's aunt. "There is no way Kari would've done this."
Lanham also said Kari Baker was excited for her future.
"The day of her death, she had gone in for an interview," Lanham said. "It went really well."
The churchgoing people of Waco viewed Matt Baker as a grieving widower left to raise his two surviving daughters and to pick up the pieces after these two terrible tragedies -- which is why it was a shock to Waco, Baker's church and his family when months after Kari Baker's death, the justice of the peace changed his ruling on the case.
At that time, Matt Baker was arrested and charged with first degree murder, and some began to wonder if he had a secret life that may have led to his wife's death.
Lora Wilson was a freshman at Baylor University along with Matt Baker in the early 1990s. They both worked in the athletic department as trainers where she said Baker assaulted her in the locker room at Floyd Casey Stadium.
"He didn't stop with the kiss," Wilson said. "He didn't stop with the touching until he was ready to stop, 'til he had gotten whatever it is he got."
Baker remembered the incident, but denied assaulting Wilson. He said it was the fantasy of a hysterical coed.
"There was a group of us working, and when we finished, I don't know what happened to her," Baker said. "All I can tell you is when she left the facility, [she] was in tears, but [it was] nothing I did."
In March 2008, "20/20" documented six other complaints against Baker -- including one by a female custodian from the First Baptist Church of Waco, who said Baker grabbed her sexually; a teenage girl from the same church who claimed he spoke to her in a sexually provocative manner; and several at the YMCA where he supervised a day camp. There, four young women complained to management of improper sexual conduct.
Baker denied all of the allegations, including any claims of assault.
"I can say this and I'll say it again that ... never once did I solicit sex from anybody," Baker said. "But can there have been things that have been said that [were] misconstrued? Possible, but never once did I solicit sex from them."
What really turned Kari Baker's family against Matt Baker was the revelation that he had given Kari's cell phone to a young woman from his church who he called every day.
A police affidavit outlining Baker's arrest accused him of having an affair with the woman and even claimed they were seen shopping for engagement rings together. The affidavit stated Baker's motive for murder was to continue his new relationship.
Baker claimed the relationship was platonic and he and the young woman were buying earrings for his daughters.
The police affidavit also claimed Kari Baker may have suspected her life was in danger.
The affidavit said she believed Matt Baker was having an affair and that she told her counselor she found crushed pills in his briefcase and was afraid he was going to poison her because he was having an affair.
Police said they found evidence on Baker's computers that he was searching the Internet about sleeping pill poisoning.
Baker said that he has no idea where the crushed pills came from and that he searched the Internet because he was trying to protect his wife, who he said was increasingly dependent on sleeping pills.
