The parents of three Portland women found dead this year are speaking out after police named a "career criminal" as a person of interest in their apparently linked murders.

Jesse Lee Calhoun, 38, has been named a person of interest in connection with the murders of four women: Kristin Smith, 22; Charity Lynn Perry, 24; Bridget Leann (Ramsay) Webster, 31; and Ashley Real, 22. Oregon authorities located their remains between February and May.

"I know she was murdered, and I have faith that the police department is going to piece this together, get that proof, and we’re able to get that justice for her and the other girls – if they are linked," Melissa Smith, Kristin Smith's mother, said in a video posted to Facebook on Wednesday, adding that police have not told her directly that the four cases are linked.

Melissa Smith said she is "very confident" in the homicide detective assigned to her daughter's case.

"I’m in the dark about a lot," Allen told AP. "But the detective and I understand why this is required. We don’t need anything messing up this investigation."

The Multnomah County Sheriff's Office previously described Calhoun as a "a prolific thief and career criminal" after he was sentenced in 2019 to four years in prison for burglaries in East Multnomah County

He was charged with three counts of unauthorized use of a vehicle, one count of assaulting a public safety officer and one count of first-degree burglary.

Prior to Calhoun's arrest for the series of thefts, he was charged with illegal firearms possession, unlawful use of a motor vehicle, and possession of a controlled substance following a 2018 traffic stop. The traffic stop led to the recovery of a stolen car, modified firearms, more than 500 rounds of ammunition and 6 grams of methamphetamine, according to police.

In 2021 then-Gov. Kate Brown commuted his sentence, along with those of 40 other prisoners. As prisoners, they had helped fight wildfires, and Brown released them after determining they did not present unacceptable safety risks to the public.

"I really hope that going forward we can get more help here in Portland… with the police department in searching for missing persons, taking it more seriously in the beginning when they're reported missing," Smith said.

"And the homelessness – we need help. We need help with this. And getting drugs off the street," Smith said, adding that "it's never going to go away if we don't make a change."
