Police are warning Northern Coloradans that 2 men classified as sexually violent predators are now living on the streets in our community.

According to the Boulder Daily Camera, Joseph Jay Halliday, 23, registered his address as the Boulder Shelter for the Homeless last month. Police are now clarifying that Halliday is homeless and "stays at bus stop benches along Broadway and Walnut Street, and around the main bus station."

For anyone that lives in or has lived in Boulder, they know how popular the bus system is compared to other parts of Northern Colorado (like the MAX in Fort Collins, for example).

Halliday was serving a work-release sentence earlier this year out of the Boulder County Jail after pleading guilty to attempted sex assault on a child and sexual exploitation of a child in a 2012 case in Boulder County. He returned to jail after violating work release terms.

He was also convicted for lewd and lascivious acts with a child under 14 in California.

Another sexually violent predator earlier this week registered an abandoned building west of Arapahoe Avenue and 55th Street as his address, the Daily Camera reports.

Michael David Smith, 47, also allegedly couch surfs at 2995 Eagle Way #24 in Boulder, according to police.

Police are required to tell the public when a "sexually violent predator" moves into the community or has a new address.
