DES MOINES, Iowa (AP) – Officials with the Iowa Department of Transportation say they’re still unsure why the agency’s first drug-sniffing dog jumped out of a truck window on Interstate 80 in October, and fled into traffic. Earlier this week, the Iowa Appeal Board approved a $1,323 payout for damages to the owners of the vehicle that struck and killed the 2-year-old Belgian Malinois named Sara. The Oct. 8 incident was ruled an accident.

David Lorenzen, chief of the department’s motor vehicle enforcement division, says Sara had been added to the department about a year before her death following a rigorous selection process. He says she was trained not to jump and may have done so out of fear. The department has since replaced Sara with another Belgian Malinois named Storm.
