SEATTLE — Daniel Couch is being sought after leaving a Seattle treatment facility while under electronic home detention, according to the King County Prosecutor’s Office, which says his GPS monitoring later stopped. Prosecutors said Sea Mar staff notified Couch’s home-monitoring officers three days before the announcement that he had been discharged from treatment. The facility did not provide further details about the discharge, according to court documents cited by prosecutors. GPS data showed Couch traveled to a home in South Seattle and did not respond to the ankle monitor’s prompts to call monitoring officers, prosecutors said. About two hours after he left the facility, authorities classified him as a “walkaway,” and the device stopped reporting his location. He has not been seen since, and a warrant has been issued for his arrest. Couch had been staying at Sea Mar Turning Point Treatment Center in Seattle’s Central District as part of an electronic home detention arrangement. He was first sent there after being jailed, but was returned to King County Jail following a violation. In September, he was placed at the facility again and required to wear a GPS monitor. The case stems from a July incident near Fourth Avenue South and Jackson Street. Seattle police say Couch tried to board a King County Metro bus, but the driver refused because he recognized Couch from an earlier machete incident. Video later showed Couch striking the bus in several places with a machete, police said. Couch was charged with malicious mischief and jailed. Prosecutors say Couch has had 44 arrest warrants over the past 11 years and is considered dangerous to the community. They said he should be in jail or treatment while authorities work with law enforcement to locate him. Electronic home detention is a court-ordered alternative to jail that can require people to wear electronic tracking devices.
