Sheehan: Tewksbury PD Breath Test Devices Working Just Fine

Tewksbury Police Department.

Earlier this week, Middlesex County DA Marian Ryan ordered her ADAs to suspend the use of breath test results in drunk driving cases, as State Police investigators looked into possible problems with the calibrations of some of the devices being used.
It is possible that these problems could result in previous drunk driving convictions in Middlesex County being overturned.
According to information on the Tewksbury Police web site, Tewksbury Police made 104 drunk driving arrests in 2014.
Yesterday, responding to a media request for comment and information, Tewksbury Police Chief Timothy Sheehan released the following statement regarding DA Ryan's announcement and the calibration of the breath test devices used in Tewksbury:

I am in receipt of the District Attorney’s press release which indicates that “in an abundance of caution” she has instructed Assistant District Attorneys in her office to suspend the use of breath test results in operating under the influence cases until further notice. One of our first calls made after hearing about the limited number of problematic cases in the Middlesex County was to the Office of Alcohol Testing to determine if the validity of any of Tewksbury Police Department’s testing would be called into question. They have confirmed that a preliminary review of the breathalyzer tests performed on our Draeger 9510 has revealed that they are all within the acceptable gas calibration standards set in the applicable Massachusetts Safe Roads CMR  (501 CMR 2.00). That being the case, the applicable CMR indicates that this would infer our testing has been valid and that our device is operating properly. At this point, we will continue to abide by the Department’s standard operating procedures in all of our OUI investigations and arrests.  We will also continue to closely monitor our calibration checks on all tests administered while this situation continues to unravel. As has been demonstrated by participation in recent sobriety checkpoints and “Drive Sober or Get Pulled Over” campaigns, we take drunk driving very seriously.
