Colorado prosecutors say a 72-year-old man suffered serious injuries when he was stabbed by a 20-year-old woman described as his "intimate" friend.

Jennifer Stroth was arrested on a domestic violence charge in Larimer County on February 17th.

Denver district attorney's spokeswoman Lynn Kimbrough says investigators found evidence the woman stabbed the man on two other occasions in Denver this month.

Kimbrough says the pair were "intimate friends" and shared a house in Denver.

She says Stroth will face charges in Denver as well.

Stroth has no listed phone number.
