The Iowa Department of Human Services has warned Ottumwa, IA residents to be careful when people claiming to be social workers show up at their homes front doors. DHS spokesman, Roger Munns, announced the agency told Ottumwa police on Thursday that at least 3 three residents within the last couple of days have let impostors into their homes after they identified themselves as department workers. Munns says the men left after residents answered questions about their families. The residents later called the agency because the questions and demeanor raised doubt. DHS representatives are required to present state issued ID badge upon requesting an interview.
