"Federal Officials Identify Casey Nocket As 'Major Suspect' In National Parks Graffiti Cases"
"LOS ANGELES, Oct 30 (Reuters) - Federal officials have publicly identified a woman suspected of graffiti vandalism in at least eight national parks across the West, including Yosemite and Death Valley in California, and credit social media for helping pinpoint the alleged culprit.
Casey Nocket of New York state has not been arrested or charged but was confirmed on Thursday as "the major suspect" in an investigation of one of the most widespread acts of serial vandalism documented in the National Park System."
The Park Service said initially it was investigating such vandalism in at least 10 Western national parks.
But agency spokeswoman Alexandra Picavet said on Thursday that Nocket had been tied as a suspect to graffiti in eight parks - Yosemite, Death Valley and Joshua Tree in California; Crater Lake in Oregon; Zion and Canyonlands in Utah; and Rocky Mountain National Park and Colorado National Monument in Colorado."
