PENDLETON — Pendleton’s most recent murder and the ensuing mystery, arrest and guilty plea is coming to television in early November.

Dateline NBC will air its one-hour TV special on Nov. 7 at 8 p.m., featuring the crimes of transient Lukah Chang. Chang pleaded guilty to the 2012 murder of teenager Amy Jane Brandhagen and the 2013 assault of Karen Lange.

Police had few leads and no suspects after Brandhagen was found dead in a Pendleton motel room in August 2012. A year later, Lange was attacked and left for dead while on a walk near the Pendleton River Parkway. Police matched DNA evidence between the two crime scenes and named a suspect — a transient known to police as Danny Wu.

It wasn’t until after he was captured hiding in the Pendleton Convention Center that police learned his name was Lukah Chang, he was a Marine deserter and he had only been in Pendleton a short time before killing Brandhagen.

NBC’s Dateline series began in 1992 as a television news magazine, but now almost exclusively features true crime reporting. The crew came to Pendleton and filmed on location in September, interviewing people close to the crime including police chief Stuart Roberts, District Attorney Dan Primus and Dan and Karen Lange.
