News Release
David Thomas Haugen charged with manslaughter in the second degree following fatal crash in Gresham, Oregon - 11/26/19

November 26, 2019

David Thomas Haugen charged with manslaughter in the second degree following fatal crash in Gresham, Oregon

On November 25, 2019, a four-count charging document was filed against 38-year-old David Thomas Haugen for allegedly causing and then fleeing the scene of a deadly crash in East Multnomah County.

Haugen is charged with one count of manslaughter in the second degree, one count of failing to perform the duties of a driver and two counts of driving under the influence of intoxicants.

According to court documents, officers assigned to the Gresham Police Department and deputies assigned to the Multnomah County Sheriff’s Office responded to the intersection of Northeast Halsey Street and Northeast 192nd Avenue on November 23, 2019 on reports of a vehicular crash that resulted in a fatality. 

Law enforcement learned that a truck traveling eastbound at a high rate of speed on Northeast Halsey Street struck 21-year-old Zachary O'Leary who was crossing the street in a marked crosswalk, according to court documents.

Mr. O’Leary was hit with such force that he flew into the air, according to court documents.

Law enforcement determined the impact threw Mr. O’Leary approximately 100 feet from the point of impact, court documents state.

Approximately 25 minutes after the crash was reported a man, later identified as Haugen, walked into the crime scene and told officers that he caused the crash, according to court documents. It was later determined that Haugen had returned to the scene in the same vehicle he was driving at the time of the crash, court documents state.

The vehicle Haugen was driving was determined to be a pickup. It was found with significant damage to the front, according to court documents.

When law enforcement contacted Haugen, he was observed with bloodshot, watery and glassy eyes and he had “a strong and distinct odor of an alcoholic beverage” coming from his breath, according to court documents.

A certified drug recognition expert conducted a drug recognition examination of Haugen. During that examination, Haugen admitted to drinking alcohol in the afternoon before the crash and to smoking marijuana in the morning.

Law enforcement determined Haugen was under the combined influence of alcohol and marijuana and was unable to operate a vehicle safely, according to court documents.

Haugen had a blood alcohol content of .11%, according to court documents.

Like in all criminal and civil matters, electronic copies of court documents, which are not subject to a protective order, are available to the public through the Oregon eCourt Information (OECI) system.

No additional information can be released by the Multnomah County District Attorney’s Office at this time pursuant to the Oregon Rules of Professional Conduct.

A charging document is only an accusation of a crime. Haugen is innocent unless and until proven guilty.
