A real estate agency will use the buddy system when showing houses following the slaying of one of its agents.

Barry Luce, an owner of RE/MAX Community Realty based in Lake Mills, says it's asking all the firm's agents to buddy up in pairs for a while when showing a house. It also wants them to meet new prospective buyers at the office first.

The agency is acting in response to the slaying Tuesday of 71-year-old Ann Nelson of Cambridge. An ex-convict from suburban Chicago has been charged in the case.

The Wisconsin Realtors Association has sent an e-mail to agents around the state with links to written materials and videos concerning safety strategies.
