Around 2230 people were reported missing across WA last year, equating to six people each day.
While many of them are found safe, other families can go months, years or even decades without knowing where their loved one is.
Hayley Dodd, Sylvia Caroline Rogerson, Raylene Eaton, and Jason Edge's families are among those still waiting for closure.
Organised by the Zonta Club of Peel, a touching memorial paid an emotional tribute to those missing on Friday morning for National Missing Persons Week.
Mandurah mayor Rhys Williams, Zonta Club of Peel president Nikki Hooper, Aboriginal community leader George Walley, Pinjarra Police Senior Sergeant Ian Francis, and Murray-Wellington MP Robyn Clarke were among those that offered their support to families missing a loved one.
Zonta Club of Peel president Nikki Hooper said the memorial offers families of missing persons a place to go to remember their loved ones.
"This is a place of comfort, solace, and reflection for those who have lost a loved one with no knowledge of where they are or what may have happened to them," she said.
"There is no conclusion for these families and friends, which causes unimaginable heartache."
Mandurah mayor Rhys Williams also addressed attendees at the memorial, he expressed the community support available to those who had lost loved ones.
"Your pain is a different type of pain, it's a pain that those of us who don't understand it, can't comprehend," he said.
"I want you to know that myself and those that are here today and the 90,000 people that live in this community are here to love you and care for you and put our arms around you and support you.
"We can't understand the grief but we can care for you and we do."

Murray-Wellington MP Robyn Clarke said some words at the service before attendees were invited to lay flowers.
"I cannot fathom what you're feeling, what you felt, and what you're still going through," she said.
"We can't stand in your shoes but we can certainly wrap our arms around you and make sure you know that we are here for you.
"These people who are missing are lost but will never be forgotten."
