An Oregon police officer working at the request of California investigators persuaded a judge in March 2017 to order a 73-year-old man in a nursing home to provide a DNA sample.

The Oregon City man is in declining health and was unable to answer questions Friday about the case.

His daughter said authorities never notified her before swabbing her father for DNA in his bed a rehabilitation center, but once they told her afterward she understood and worked with them to eliminate people who conceivably could be the killer.
