Three months after Tyler Krebs resigned as the head coach for the Lakeville South High School football team, charging documents reveal that Krebs accessed email login information of a head coach at a rival school. 

According to a criminal complaint, Krebs is accused of accessing Eastview High School football coach Kelly Sherwin's email and Hudl account, which the complaint says is used for sharing and analysis involving the school's athletic teams. 

Sherwin, who is identified by his initials in the complaint, contacted police Sept. 19 reporting that a message was sent to the entire Eastview football team and coaching staff from his email, informing a change in practice time and use of turf fields. Sherwin contacted the team and said he never the sent the email and that practice plans were not changed.

Sherwin believed someone from a Lakeville school accessed his account and "sent the message to confuse the team," the complaint says. He was under that impression because Eastview was scheduled to play Lakeville South that week. 

Lakeville South, which has access to turf fields, had practice times that matched the times sent in the email from Sherwin's account. 

Sherwin was able to get Hudl to confirm that the suspicious message was sent from an IP address at Lakeville Public Schools, with Krebs accessing Sherwin's account at 7:47 a.m. on Sept. 19, with the message sent at 8:04 a.m. 

Records revealed that Krebs frequently accessed Sherwin's school email account dating back to Mar. 4, and Krebs' internet history also revealed that he used the internet to search "6 Times the New England Patriots Allegedly Cheated in Big Games” and “bill belichick cheater.”

Belichick and the Patriots have long been accused of using different techniques to cheat, including spying through video cameras and deflating footballs. 

Krebs admitted to a Lakeville Public Schools activities director that he accessed Sherwin's accounts, saying he was able to do so because he had login information from his time working on Sherwin's coaching staff in the past. 

Krebs added that any time Sherwin changed his login information, he was able to determine the new password and maintain access. 

Krebs apologized to Sherwin through a voicemail and text message, acknowledging that he damaged both football programs. 

Krebs was charged Thursday with a misdemeanor for unauthorized computer access, which can carry a punishment of up to 90 days in jail and/or a fine of up to $1,000.
