A man accused of shooting a woman and man with a blow dart in two separate attacks in Washington state has made his first court appearance on assault charges.  

KREM-TV reports 18-year-old Joseph Gillies of Tacoma appeared in court in Whitman County. He was released from jail until his next court appearance.

Gillies is accused of shooting a woman with a blow dart Jan. 12 on the Washington State University campus. He’s also accused of hitting a man with a dart two days later while walking in Pullman.

Police say they suspect Gillies of several similar blow dart assaults in Ellensburg.

Gillies told KREM he’s sorry for the dart attacks but offered no explanation other than saying, “I’m a moron.”

Tips and surveillance video led to Gillies’ arrest in Ellensburg.

No serious injuries were reported.
