Officers described him as drowsy, moving slowly, and taking a long time to respond to questions. Klein said he had not been drinking, but noted he took his Adderall prescription at 5:30 a.m.
Deputies asked Klein to get out of the car to perform several field sobriety tests. Klein used the car door to balance himself and had a hard time standing upright, according to the criminal complaint.
He failed all three sobriety tests, including a heel-to-toe walk in which Klein didn't make proper foot contact, made a wrong turn, and counted to 12 instead of 10.
Police arrested him on suspicion of driving while intoxicated. They searched Klein and found a pill bottle with seven different prescription pills, including some narcotics like Acetaminophen Hydrocodone (a schedule II narcotic), Alprazolam (a schedule IV controlled substance), and an anti-psychotic drug.
Klein was placed on paid administrative leave on March 27. Jacobi said he is still on paid leave as of Wednesday. Klein is in his sixth year teaching with SDR, according to his online biography.
Jacobi said further discussions about Klein's future with the district will be decided once court proceedings play out.
Klein will enter a plea to a felony narcotic drug possession and misdemeanor controlled substance possession charges May 20.
