A 39-year-old man was shot and killed in Tacoma on Friday night, according to Tacoma Police. 

Police say 911 received reports of a robbery in the 6600 block of South Alaska Street shortly after 11:30 p.m. and one person was shot. 

After police attempted life-saving measures, the Tacoma Fire Department declared the man deceased at the scene, the Tacoma Police Department said in a news release. Three armed suspects fled the scene, police said.

Police believe the suspects were attempting to rob people experiencing homelessness who were living in an encampment just off the roadway, said Tacoma Police spokesperson Wendy Haddow. 

Police said they are investigating the case as a homicide, but did not immediately release further details.
