Mihail Petrov, 38, was found guilty of 1st Degree Murder and seven other charges related to Weatherly’s death.

“He dumped her body like garbage,” District Attorney George Brauchler. “There is no room in our society for such a monster.”

According to prosecutors, Petrov’s fingerprints were found on items around Weatherly’s body, Weatherly’s blood was found on Petrov’s clothing and car interior, and Petrov bragged to two people he had killed someone.
