Client stopped for speeding violation on highway and is arrested for OUI. Post arrest breath test discloses .09 BrAC. Arrest report does not disclose involvement of any other person or driver at scene of arrest. Defense investigation through alleged drunk driver intake reveals second motorist stopped in the breakdown lane at scene of client’s stop, engaged police with requests for directions, and was then arrested at scene for possession charge and transported and booked with client. Defense raises police failure to disclose “two for one” arrest scene or identity of witness. OUI charge dismissed for lack of prosecution.
