Boulder County law enforcement today notified the community of two court-designated sexually violent predators — both with a history of sex crimes against children — who will be released into or residing in Boulder.

Joseph Jay Halliday, 22, is serving his work-release sentence out of the Boulder County Jail in Boulder after pleading guilty to attempted sex assault on a child and sexual exploitation of a child in a 2012 case in Boulder County, for which he also served a prison sentence.

Halliday will be working in Boulder County during the day and spending his nights at the jail, but according to a bulletin from the Boulder County Sheriff’s Office, he is still looking for employment.

He also has a conviction for lewd and lascivious acts with a child under 14 in California.

Halliday is not permitted to be in contact with any juveniles and may not be at schools, playgrounds, arcades, pools or any other locations used primarily by children.

He was determined to present a “high potential to re-offend,” according to the bulletin.

Police also announced that Kerry Fitzgerald Whitfield, 51, who works in Aurora, will be in the Boulder area because he “parks his van, and motorhome, in various parking lots throughout the city of Boulder.”

Whitfield pleaded guilty to attempted sexual assault on a child in Denver in 2004. He also was arrested in Boulder in 2011 for failing to register as a sex offender, to which he pleaded guilty.

Whitfield was also previously denied work-release in Boulder County.

He currently is free and no longer serving any sentence.

Local law enforcement agencies are required to notify the community when people who have been declared “sexually violent predators” by the courts will be moving into their jurisdictions.
