DHS-OIG INVESTIGATIONS

Summary
Amends the Department of Human Services Act. In the definition of "material obstruction of an investigation", defines the term to mean the intentional failure to timely report an allegation to the hotline or the interference (rather than purposeful interference) with an investigation of physical abuse, sexual abuse, mental abuse, neglect, or financial exploitation for the purpose of obstructing an Office of the Inspector General investigation. Provides that such material obstruction may include, but is not limited to, delaying or withholding reports of allegations to the hotline for the purpose of obstructing an Office of the Inspector General investigation; the withholding or altering of documentation or recorded evidence when reporting an allegation to the hotline or during an investigation; influencing, threatening, or impeding a victim's, complainant's, or required reporter's report of an allegation to the hotline or witness testimony during an investigation; or presenting untruthful information to the hotline or during an investigatory interview. Provides that any employee who fails to cooperate with an Office of the Inspector General investigation may also result in a finding of material obstruction of an investigation. Expands the list of employee conduct during an investigation that is in violation of the Act, including the failure to timely report an incident of abuse or material obstruction of an investigation committed by another employee. Makes changes to the definition of "presenting untruthful information".
