Two Gresham residents are dead Saturday in what police say is a likely murder-suicide.

According to the Gresham Police Department, 35-year-old Robert Lopez shot his girlfriend to death, then no more than 20 minutes later, killed himself.

At 8:25 p.m. Saturday, Lopez's father walked into the Gresham Police Department lobby and told cops on duty that his son had just killed Hillary Vodden, 34. Police went to the house where Lopez's father said the crime occurred, at the 2000 block of Northwest 7th Place.

Vodden was dead when police arrived.

Meanwhile, the Multnomah County Sheriff's Office responded to the scene of a car crash on Highway 26 at Southeast Haley Road. There, they found Lopez behind the wheel. Police said he had shot himself. They did not say whether the car crashed before or after the shot.

The car belonged to Vodden.

Lopez had been found guilty of harassment and disorderly conduct in 2002, which required him to undergo treatment for alcohol abuse. He had also been convicted several times of reckless driving and driving under the influence of alcohol or drugs, as recently as 2013. He was found to have violated his parole in 2016.

Police are asking that anyone who witnessed either shooting or has information that could be important to the investigation to call an anonymous tip line at 503-618-2719 or toll-free at 888-989-3505.
