Three teenagers were arrested on suspicion of killing a 79-year-old grandmother in her home in Willmar, Minn., authorities said Thursday, easing some residents’ fears but raising new questions about the motive.
Preliminary autopsy results show that Lila Warwick was stabbed multiple times and strangled before she was found late Monday afternoon, said Kandiyohi County Sheriff Daniel Hartog. The 19- and 16-year-old suspects, both from Willmar, were arrested about 10 p.m. Wednesday. A 17-year-old boy from Willmar was arrested about 1:15 p.m. Thursday.
The case shocked Willmar, a city of 19,500.
