Two teenagers, ages 19 and 16, were arrested late Wednesday night in Willmar, Minn., in connection with the murder of 79-year-old Lila Warwick.
Warwick, who lived alone, was found dead Monday when deputies were called to her home off Highway 12 to check on her well-being.
According to Kandiyohi County Sheriff Dan Hartog, the two suspects and Warwick knew each other.
Warwick was supposed to pick up her daughter Monday morning but never showed up. Later that evening, fellow volunteers at Redeemer Lutheran Church got concerned when Warwick didn't turn up for her volunteer duties.
"There was a gracious person at church who knew it wasn't like my mom to not show up," said Cheri Ekbom, Warwick's daughter.
The preliminary autopsy results show Warwick had multiple stab wounds and neck injuries consistent with strangulation.
The two teens arrested in the murder were booked into jail on charges of second-degree murder and first-degree burglary. Both suspects are awaiting court hearings for formal charges from the Kandiyohi County attorney.
The 19-year-old suspect, Brok Junkermeier, has a criminal record that includes multiple theft charges. He was arrested from his job at West Central Tribune while the 16-year-old was arrested at his home.
