An investigation into Highlands Ranch High School's head football coach - who resigned abruptly a day after the Douglas County Sheriff's Office reported suspicious activity during a drug search at the school's student parking lot - has found no criminal activity.
The case has been closed, said Sgt. Lori Bronner, a spokeswoman for the sheriff's office.
The incident began at 9:32 a.m. on Aug. 24 when Deputy Ryan Wood, the school resource officer, informed the coach of three years, Mark Robinson, that K-9 units would be at the school at 10 a.m. to complete a sniff operation in the parking lot, according to the sheriff's office report. Robinson told two school security officers that he was leaving to put gas in a student's car and returned without the car, the report said.
School security officers informed Wood that the student's car was parked in front of Robinson's house, located behind the high school. A K-9 unit was sent to the car and had a positive hit for drugs, the police report said.
When asked about the car, the student said he left it at home that day, but couldn't remember what street it was on. He then acknowledged that it was parked at "coach's house," according to the report. The student declined to allow deputies to search his car.
Robinson, who was hired in March 2014, resigned Aug. 25. He sent a letter to Highlands Ranch High School parents on Aug. 28, stating that in the past year he has "gone through a lot of things" and "noticed that I was slipping in my duties as the head coach."
"I believe that you need to be in it 100 percent just like you ask of your players," Robinson wrote. "At this time I am unable to give that effort and after conversations with my wife and (Highlands Ranch High School principal) Dr. Page I made this decision."
The school's athletic director, Preston Davis, declined to comment on Robinson's resignation. Robinson, reached later, also declined to comment.
