PARIS — Maine State Police Officer Lauren Edstrom is expected to testify in Oxford County Superior Court on Tuesday in a hearing to overturn manslaughter charges against 21-year old Kristina Lowe.

Trooper Edstrom, a detective with Major Crimes, will be called to testify two weeks before the bulk of the hearing on July 31 because she will be on vacation.

In May, Lowe was convicted on two counts of manslaughter and one count of leaving the scene of an accident following a high-speed crash that killed West Paris teens Logan Dam, 19, and Rebecca Mason, 16, in 2012.

Prosecutors are seeking 10-year concurrent sentences for each manslaughter charge with all but five years suspended with four years of probation and a consecutive sentence of five years, all suspended, with one year of probation for leaving the scene of an accident. A sentencing date has not been scheduled.

Shortly following the conviction, defense attorney James Howaniec motioned to have the charges overturned, arguing the state’s evidence failed to meet the burden of proof. 

Howaniec has requested a full transcript from the trial, as well as previously unheard dispatcher audio and computer records which may contain contain police accounts of road conditions at the scene of the accident.

During the trial, prosecutors presented an audio recording between Edstrom and Lowe five hours after the crash in which Lowe admitted to drinking two shots of Jagermeister, but initially denied driving the car at the time of the crash.

Lowe had been given several doses of painkillers before she consented the interview, and medical examiners testified she did not appear intoxicated during treatment. A blood alcohol test later showed her BAC was .04 — below the legal limit — and tested positive for marijuana.

The interview featured heavily in the state’s case. Lowe told Edstrom more than a dozen times that Jacob Skaff, 24, was driving the 2002 Subaru Impreza. However, Lowe wavered when pressed by Edstrom and by the end of the 34-minute audiotape, Lowe could be heard telling Edstrom that she and Skaff may have switched seats when they stopped at The Big Apple in West Paris minutes before the accident.

Lowe was not read her Miranda rights prior to the interview, and the Maine Supreme Judicial Court that some of what Lowe told Edstrom on the tape, including a statement that she had been texting and driving at the time of the crash, would not be admissible in court.

That information was instead provided by Kristina’s father Earl Lowe, who told jurors that prior to the recorder being turned on his daughter told him and her mother, Melissa Stanley and Edstrom that just before the accident she heard her phone ring and looked down, which was when the car began to drift and Dam reached over from the back seat to correct the direction of the car. 

In the motion for acquittal, Howaniec said a forensic cellphone expert was unable to determine whether Lowe had received or sent a text message in the moments prior to the crash.

Edstrom is expected to testify at 1 p.m.
