Tuesday marks the one year anniversary of the deaths of Charlie and Braden Powell.
Their tragic and unexpected deaths still leave a hole in the hearts of their family. The two sons of missing West Valley City mom Susan Cox Powell died in a house explosion at the hands of their father, Josh Powell, in a murder suicide.
It happened in Washington state during a supervised visit with their father.
West Valley City Police had considered Josh Powell a "person of interest" ever since Susan disappeared on December 6, 2009.
Lawmakers in Washington state are now proposing a new law, named after Charlie and Braden. It would restrict contact between children and parents if a parent is a suspect or person of interest in a murder investigation. The bill is sponsored by Sen. Pam Roach.
"I think it's exactly what needs to happen because this tragedy didn't have to happen," said Kiirsi Hellewell, friend of Susan Cox Powell. "If Josh had been in a locked-down, secure place to have a supervised visit with his kids, I don't think it would have happened."
The boys' grandparents, Chuck and Judy Cox, still mourn the loss of their grandsons, as they continue to search for answers of Susan's disappearance.
In Utah, a vigil remembering the boys will be held at West View Park in West Valley City Tuesday at 7 p.m.
A memorial is also planned in Washington state to pay tribute to the boys.
