There are often times when police officers have to rely on anonymous callers who dial 911 to tip police off on a crime they had observed. Whenever a defendant is arrested as a result of such a tip, the trial court must determine the caller’s reliability before allowing the case to proceed to trial. In the case of Com. v. Depiero, the Appeals Court determined that it was lawful for police to arrest a driver with a history of drunk driving after receiving an anonymous 911 call reporting erratic driving.
The 911 Call
Police dispatch received a call stating that a “drunk driver” operating on Memorial Drive was “swerving all over the road.” The caller did not identify him/herself, but did provide the dispatcher with a license plate number, make, and model of the car. A state trooper was then dispatched to the driver’s address, where he observed the driver pull into his driveway. After the driver parked, the officer turned on his emergency lights and conducted a traffic stop. The driver admitted to having drunk alcohol, and subsequently failed the field sobriety tests.
