OLATHE, Kan. (AP) — Police say officers fatally shot a man outside a suburban Kansas City retail store after he hit one of them with a long wooden rod. 
  
 Lenexa, Kansas, police spokesman Dan Friesen says the man was shot near a Wal-Mart in Olathe around 10:30 p.m. Sunday after striking an officer. 
  
 Friesen, speaking on behalf of Olathe police, says the rod resembled a martial arts bo stick. 
  
 He says officers responded to a report of a man with a weapon and tried to use non-lethal force to subdue him, including an attempt to use a stun gun, but those measures were not effective. 
  
 The officer hit with the stick was treated and released at a hospital. Friesen says the dead man's identity was being withheld while authorities searched for next of kin. ||||| A special team of investigators is looking into Sunday night’s fatal shooting of a 50-year-old man by Olathe police. 
  
 The shooting happened at the Walmart store near Kansas Highway 7 and Santa Fe Street.

 Police said they were called to the store earlier in the evening about a man who was on the premises, but they didn’t find him. When they were called to the store a second time, they found the man around the side of the building. 
  
 Police said the man attacked police with a long, cylindrical weapon he had in his hands. Police said it was similar to a martial arts bo staff. 
  
 “I don’t know the composition, whether it was wood or metal,” said Officer Dan Friesen, of the Lenexa Police Department. “I think typically, those types of things are made out of wood.” 
  
 A witness said police used a Taser on the man, but it didn’t stop him. 
  
 At one point, police said the man ran toward the front of the store. 
  
 “On my left, I heard a ruckus of people running and people shouting,” said witness Graem Murray, who was coming out of the store. 
  
 He said someone told him to back inside. As he did, he said he saw the man running toward the store and holding something. He said he then heard four distinct pops. 
  
 “It wasn’t loud. It was jarring,” Murray said. 
  
 “He was running away from the officers, but then he turned toward them and attacked them directly,” Friesen said. “I believe that's why they fired.” 
  
 The man died of his injuries. He was later identified as Walter R. Echols, 50, of Cypress, Texas. 
  
 Murray said he didn’t realize the man had died. He said he’s still trying to process what he saw late Sunday. 
  
 “Honestly, when I walked out and saw the Taser leads on the ground, I thought that the dude was just tasered and that was it,” Murray said. “I’m still barely collecting myself this afternoon.” 
  
 One officer was treated for minor injuries at a hospital. 
  
 Earlier in the day on Sunday, police got a report of a man behaving strangely on a nearby walking trail. They said they’re working to find out whether it’s the same man. 
  
 Special investigative teams are assigned when police-involved shootings happen per normal procedure.
