PENDLETON, Ore. - Pendleton Police are looking for a man who officers believe is linked to two violent crimes.
Officers say 23-year-old Danny Wu assaulted 53-year-old resident, Karen Lange earlier this month. Officers now believe Wu also had something to do with the stabbing murder of 19-year-old Amy Jane Brandhagen in August of 2012, but records of Wu's DNA do not exist in the national database.
"There is no one in the CODIS system, which is the combined DNA index system, which is the national DNA database, by the name of Danny Wu," said Pendleton Police Chief Stuart Roberts.
Police say Wu attacked Lange in the Umatilla River Parkway, leaving her unconscious with head injuries. She remains in critical condition at a hospital in Portland. Officers say surveillance videos caught Wu stalking Lange with what appears to be some kind of weapon behind his back. Detectives say the recovered a section of galvanized pipe, which forensic analysts have confirmed as the assault weapon.
Oregon State Police forensic personnel no say they've matched the DNA found on that pipe to DNA found at the scene of Brandhagen's murder.
About one year ago, police found the body of 19-year old Amy Jane Brandhagen in a Pendleton motel, where she had worked for one week as a housekeeper. Officers say Branhagen had been stabbed multiple times in the chest.
Police say since Wu began living as a transient in the Pendleton area around the time of Brandhagen's death, officers have had contact with him 27 times. Police say most of his crimes were criminal trespassing, illegal lodging, outstanding bench warrants and other violations of City Ordinance. Police say Wu is a should be considered extremely dangerous.
People like Alan Simmons, who lives in Pendleton say they had seen Wu walking the parkway trail many times, but he hasn't been seen since the assault was reported.
"We always say hi, how you doing to people we pass and he always says hi back and keeps going about his business," said Simmons.
Officers say Wu is a loner, who does not usually associate or talk with other people. Detectives say Wu frequently goes to public libraries, and tends to carry knives, screwdrivers and/or weapons. If you have any information about him, contact the Pendleton Police Department at (541) 276-4411.
