Betsy Faria, however, was extremely weak when Pam Hupp picked her up from a chemotherapy appointment that day to drive her home, according to NBC News. Faria had made plans with a different driver, but accepted the ride from Hupp. When she arrived home, prosecutors now say, Hupp stabbed Faria over 50 times. She then allegedly dipped Faria’s socks in her blood and mopped them all over the house, in order to make it look like Faria had run through the home after a domestic dispute, prosecutors allege.

The effect was that Faria’s daughters felt like their hunches about Hupp had to be wrong. “They kind of made me stupid for asking,” Mariah said to Fox 2 Now. “So as a 17-year-old just kind of trying to figure out this whole process, they just kind of made my feelings feel invalid.”

Per KSDK, Lincoln County Prosecutor Mike Wood, who is overseeing the newly reopened case, agreed with the sisters’ take on how their hunches were treated, calling the original investigation “confirmation bias in its purest form, largely driven by ego.”
