The fiancé of a Colorado pilot who went missing on Thanksgiving Day has reportedly been arrested.

According to KRDO, Patrick Frazee, who is engaged to Kelsey Berreth, was seen being taken away in handcuffs from his 35-acre ranch in Florissant, Colorado, early Friday morning.

Frazee is believed to be the last person to see Berreth on November 22, when he met with her to pick up their 1-year-old daughter. The couple does not live together; Berreth lives about 15 miles away from Florissant in Woodland Park.

Authorities had made repeated visit to both Frazee’s property and Berreth’s townhouse this week, but had not officially named Frazee a suspect.

KRDO reports that sources have said police believe Berreth is no longer alive.

This is a developing story. CrimeOnline will provide updates when more information is available.
