The last person allegedly involved in the murder of Gregory "Sky" Erickson goes on trial today in Spencer. Juan Humberto Castillo-Alvarez faces second degree murder and kidnapping charges. He’s also charged with conspiracy to commit a forceable felony.
The charges were filed in 1997 after Erickson’s body was found in a rural Jackson County, Minnesota farm house. Erickson died as a result of gunshot wounds in early June that year. Authorities allege Erickson was kidnapped from Spencer, beaten and later killed in Minnesota. Castillo-Alvare was extradited him from Mexico late last year.
