Brok Junkermeier pleaded guilty this afternoon to first-degree premeditated murder for killing Lila Warwick last summer.

Action in Junkermeier’s jury trial was delayed as the 19-year-old met with attorneys and Judge Donald Spilseth in chambers. Junkermeier then took the stand and changed his plea, admitting that he and Robert “Robbie” Warwick planned the murder of Warwick's 79-year-old grandmother.

Spilseth set the sentencing for 9 a.m. next Wednesday, allowing time for the Warwick family and other victims to prepare statements for the hearing.

Junkermeier’s $2 million bail was revoked and he was ordered held until sentencing. The penalty for first-degree murder is life in prison.

Junkermeier and Robert Warwick, 18, were both indicted on first-degree murder charges in September for their roles in killing Warwick, 79, on July 29, 2013, at her residence on the east edge of Willmar.
