 Minnesota News Network. I'm Bill Werner. The Dakota County Sheriff's Office says the boyfriend of a missing woman from Randolph in southeast Minnesota is a person of interest in the case jailed on an unrelated warrant. Authorities say 56-year-old Nicole Nikki Anderson left home Saturday morning without her glasses, cell phone, or wallet and hasn't been heard from since. Deputies say Anderson's 42-year-old boyfriend was questioned Wednesday about her disappearance and remains in custody on a probation violation warrant out of LeSueur County.
