Three senior men were arrested last week as part of an ongoing investigation on internet crimes against children.

The three brothers, who are 78, 79, and 82 years old, were arrested in a North Seattle home for sexual exploitation of a child.

A family member had found materials depicting child sexual abuse while cleaning the suspects’ home, and alerted the police.

During a search of the home, Seattle Police’s Internet Crimes Against Children Section found children’s clothing that looked like it had been used, including shoes, socks, and underwear, images of child sexual abuse, and graphic descriptions of extreme harm to children.

On Wednesday, Grays Harbor County Undersheriff David Pimentel said that detectives are looking into a possible connection between the men and the case of missing 10-year-old Lindsey Baum.

Authorities believe the brothers owned a property about 20 miles away from where Baum went missing in June 2009.

Police do not have any evidence currently linking the brothers to the missing child, but they're looking at every possibility since it's still an active case.
