(CNN) -- Investigators in Washington state are looking for three young men who disappeared after leaving work together.
The three friends worked together at a florist's shop in Seattle. Their families have not seen or heard from them since they left work in a 2007 silver Chevy Silverado on Sunday afternoon, the police in Lakewood, Washington said Wednesday.
Authorities found the Silverado at an apartment complex in Kent, Washington northeast of Tacoma -- the men were briefly seen there, as well -- but there has been no known sighting of them since, police said.
Their families reported them missing on Monday.
"It is out of the ordinary for them to not have contact with their families and their disappearance is suspicious," the police statement said.
The men lived in or near Tacoma, Washington, which is about 30 miles south of Seattle, in the northwestern part of the state.
Police identified the missing men as Jesus Bejar Avila, 24, of Lakewood, Washington; Yazmany Quezada Ortiz, 25, of Tacoma, Washington and Christian Alberto Rangel, 19, of University Place, Washington.
