Police are saying that the abduction and killing of a 10-year-old girl in suburban Denver this month is connected to a kidnapping attempt against a young woman earlier this year.

Authorities aren’t releasing any details about that link but Westminster investigator Trevor Materasso said Tuesday that they’re looking for a suspect in connection with both cases that they describe as “a light-skinned man” between 18 and mid-30s of average height and build.

Jessica Ridgeway disappeared Oct. 5 after leaving for school. Her body was found five days later in a nearby field.

Police say a 22-year-old woman reported escaping from an attacker who grabbed her from behind and put a rag over her mouth that had a chemical smell while she jogged by a lake near Jessica’s school in May.
