City of Ames officials updated the city council Tuesday on steps being taken to make the city safer after last week's murder of Iowa State University student Celia Barquin Arozamena. Police Chief Chuck Cychosz says the parks and recreation department is working to better light pedestrian and bike paths as well as removing brush from trails where potential assailants could hide. He says they're also working with a number of local agencies to curb homeless people camping in city parks and on private property. The man suspected of killing Barquin Arozamena was homeless at the time of the crime. He says the police department's message to the community is the same today as it was before last week's murder--if you see something, say something.
