A Minnesota woman who was reported missing six months ago was likely killed by a single gunshot wound to the head before she was buried in a shallow grave, police said.
The remains of Mandy Matula, 24, were found Saturday afternoon by a hiker at Mississippi River Park in Stearns County, Minnesota.
According to police in Eden Prairie, Minn., the remains were wrapped in a blanket along with several personal effects, including Matula's high school class ring and a University of Minnesota-Duluth softball pullover embroidered with the number 14.
Matula was reported missing the evening of May 1. She was last seen with her ex-boyfriend, David Marshall Roe, who police have named a person of interest in the case.
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.
"This may have put a bad image on Dave, but Dave, he was such a really good guy. He was a sweetheart. 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."
