HUMBOLDT, Iowa —  Hundreds of people are mourning the deaths of two clerks who were killed  at different convenience stores in northern Iowa.

KCCI-TV of Des  Moines says a big crowd braved the cold for a candlelight vigil  Wednesday night at the Kum and Go in Humboldt, where clerk Sheila Myers  was shot during a robbery Monday night.

About an hour earlier, Vicky Bowman-Hall was shot during a robbery at a convenience store in Algona.

Residents say one of the toughest things is the loss of innocence in the community.

A  Minnesota teenager, Michael Richard Swanson, of St. Louis Park, is  charged with first-degree murder and first-degree robbery in the women’s  deaths.
