The estate of a 31-year-old woman who died after dashing across a downtown freeway on her way to a homeless camp filed a $2 million lawsuit against the drunken driver who hit her.

The woman's 45-year-old fiance, who was struck in the head by the driver’s sideview mirror but survived, also filed a $2.5 million lawsuit Wednesday for his injuries and the trauma of seeing his fiancee die along U.S. 26 near the Vista Ridge tunnel.

The driver, 67-year-old Brent McCune, was convicted of hit-and-run driving and driving while under the influence of intoxicants in the death of Savannah Munden.

The Multnomah County District Attorney's Office didn't pursue homicide charges after determining there wasn't evidence that a sober driver could have avoided crashing into Munden and Timothy Berg between 10 p.m. and 10:30 p.m. on Aug. 8, 2016.

McCune fled and drove to his Beaverton home, then called 911 to turn himself in. His blood alcohol level was .22 percent when police measured it that night. The legal limit for driving is .08 percent.

Investigators weren't able to determine whether the impact of McCune’s car killed Munden or if it was the impact of a second car behind McCune’s that caused her death. The second driver stopped, stayed at the scene and wasn’t charged with any crimes.

McCune couldn't immediately be reached Thursday for comment on the lawsuits.

Although the lawsuits don’t describe the housing status of Munden and Berg at the time of the crash, they were featured in The Portland Tribune as a homeless couple living along Interstate 405 eight months earlier.

The suits say that at the time of the crash, they were planning to walk up the freeway's median toward downtown to visit a friend living at a homeless camp.

A probable cause affidavit filed by the prosecution in McCune’s criminal case says the two were hit while “crossing” the on-ramp from I-405 to Highway 26. But the suits say Munden and Berg already had crossed the on-ramp and were walking along the freeway’s shoulder when McCune’s 2009 Volkswagen Jetta drifted over the fog line and struck them.

“McCune was at a safe distance, with a clear line of sight, and enough time to react, to see Savannah Munden and Timothy Berg walking in the shoulder adjacent to his lane of travel long before he reached their vicinity,” the lawsuits say.

Last May, McCune was sentenced to 30 days in jail, three years of probation, 200 hours of community service, an evaluation to learn if he has drug and alcohol problems and treatment if necessary. His driver's license also was suspended for five years.

Munden’s mother, Kim Munden, filed the lawsuit on behalf of her daughter’s estate. She told The Oregonian/OregonLive after McCune’s sentencing hearing that she was upset that McCune didn’t stand up in court and apologize.

Kim Munden also said she didn’t think 30 days in jail was justice.

“Somebody takes a life, he does 30 days -- that’s wrong,” Kim Munden said. “He should have at least got bloody manslaughter. ... I’m without a daughter and he’s inconvenienced.”

Savannah Munden died at the scene. Berg suffered soft tissue damage, a traumatic brain injury and a concussion, his suit states.

Berg seeks $500,000 for past and future medical expenses, lost wages and future diminished earning capacity. He also seeks $2 million in emotional distress.

The suits were filed in Multnomah County Circuit Court. Tigard attorney Travis Mayor is representing Munden's estate. Clackamas attorney Joshua Callahan is representing Berg.
