The document includes a DEA case number and lists the case‘s opening date as Dec. 17, 2010 in New York. It notes that the matter is „judicial pending,“ indicating that the investigation remained active at the time the memo was drafted 5 years later. One law enforcement source told CBS News that this designation suggests investigators may have been awaiting court approval for search warrants or other legal action.

Another law enforcement source said it likely meant an arrest of someone associated with the case had been made. CBS News could not confirm that because the names of other targets were redacted from the document.
