CLARK COUNTY, WA (KPTV) -

Detectives are hoping to learn the name of a man who is believed to be one of the last people to see a 17-year-old girl alive in 1974.

The Clark County Sheriff's Office Cold Case Unit is once again asking for the public's help to bring Martha Marie Morrison's killer to justice.

They believe her boyfriend at the time of her death may be able to help.

Detectives said the man is not a suspect in the case. However, investigators want to talk to him to possibly piece together the last days and hours of Morrison's life.

Investigators said the couple met at a job-training program in or near Phoenix, Arizona. They drove to Portland in the summer of 1974 and met with Morrison's family in Eugene on the way.

One day in September 1974, the couple had an argument. After her boyfriend went to work, Morrison was seen leaving their Portland apartment with some of her belongings.

Her body was found two months later in a shallow grave in the Dole Valley area of east Clark County. The identity of the remains remained unknown for 41 years, until DNA testing confirmed it was Morrison in July 2015.

Family members told detectives they only met her boyfriend twice, once briefly as the couple drove through Eugene and then several weeks later when he visited them as he looked for Morrison after her disappearance.

Family members have said they don't remember his name or where the couple lived in Portland.

He is described as 5'7" to 5'10" with a slender build. Deputies said he may have been African-American.

Morrison is described as 5'4" and 140 pounds. She had thick, long brown hair and bad psoriasis everywhere except her face.

She frequented coffee houses, where she would sing or play guitar. She was also proficient in American Sign Language.

Anyone with information about the former boyfriend or this case is asked to contact Clark County Sheriff's Office Detective Craig Marler at 360-397-2108 or craig.marler@clark.wa.gov. Tips can also be left on the Cold Case Tip Line at 360-397-2036.
