Three people have been arrested on suspicion of murder in the slaying of a 79-year-old church volunteer and great-grandmother who was found dead earlier this week in her Willmar home, authorities said Thursday.
Kandiyohi County Sheriff Dan Hartog also said preliminary autopsy results show Lila Warwick had multiple stab wounds and neck injuries that were consistent with strangling.
Warwick, who lived alone, was found Monday after authorities went to her home to check on her welfare.
Hartog said a 17-year-old boy was arrested Thursday around 1:15 p.m. in connection with the homicide of Warwick.
This comes after a 19-year-old man and a 16-year-old boy were arrested late Wednesday on suspicion of murder and burglary.
All three suspects are from Willmar. Hartog said the 19-year-old could be charged Friday morning.
Warwick was a volunteer at Redeemer Lutheran Church, where she helped with office duties and vacation Bible school. Deputies went to her house Monday after someone from the church requested a welfare check.
Warwick had eight grandchildren and two great-grandchildren.
