Murder trial for killer Warren Forrest underway

PORTLAND, Ore. (KOIN) — A long-awaited and often-delayed murder trial for convicted killer Warren Forrest finally got underway in Clark County.

Jury selection began Monday morning in the trial connected to the death of Martha Morrison in 1974. The trial, expected to last 3 weeks, could have nearly 100 witnesses called to the stand, 2 of whom survived attacks by Forrest decades ago.

Lawyers spent most of the day picking a jury.

KOIN 6 News learned the early days of the trial are likely to focus on witnesses from Forrest’s past crimes, including 2 survivors.

Forrest, now 73, was initially charged in 2019, but the pandemic delayed the trial multiple times. Additional delays were caused when the lead prosecutor became a judge.

In pre-trial motions, the defense argued jurors should not be allowed to hear about evidence from Forrest’s previous convictions, including the kidnapping of a 20-year-old woman from Portland who he took to Lacamas Lake, brutally raped, and left for dead. Evidence from that attack is what ties Forrest now to the murder of Morrison.

Forrest, a former county parks employee, admitted to using a dart gun to shoot the Lacamas Lake victim on Oct. 1, 1974.

In 2015, through DNA, the Washington State Crime Lab identified a stain on the dart gun as Morrison’s blood. Her body was found 20 miles away from Lacamas Lake, in remote NE Clark County in a clearing off of Dole Valley Road.

The judge ruled the dart gun and other Lacamas Lake evidence can be used against Forrest when he faces a new jury, 48 years after Morrison disappeared.

If Forrest is found guilty, it will only be his second murder conviction even though he’s suspected of killing 7 women and girls from Portland and Clark County, and attacking two more who survived.
