Roe had agreed to speak with investigators but shot himself in the head in the parking lot of the Eden Prairie City Center on the afternoon of May 2 before he could be questioned. Steven Matula, Mandy's younger, brother, told ABC News" Minneapolis affiliate KSTP-TV that even though Roe could have been involved in his sister's death, he wasn't bitter. He was a good brother, good friend, a mentor just like Mandy," Matula said. No one would have ever expected for this to happen from him.
