Chilling video shows woman walking home with boyfriend just before he allegedly killed her

Chilling footage showed a nurse walking home from the grocery store with her boyfriend in Seattle before he allegedly killed her while high on drugs, officials said.

Andy Chu, 26, confessed to killing his girlfriend Zoey Suyun He, while she was visiting from Hawaii over the weekend, according to the King County Prosecuting Attorney’s Office.

Chu allegedly twisted her neck and held her underwater in a bathtub, prosecutors said. An autopsy revealed He also suffered blunt force trauma to her head, face, neck, chest and limbs — and a golf ball was lodged in her throat, KOMO News reported.

A neighbor’s security camera provided footage that showed Chu and the victim walking into the townhome with groceries on Aug. 9. 

The next day, Chu left the house alone was seen on camera pulling something out from under his shirt, wrapped in what appeared to be a towel as he left the home, Fox 13 reported.

Later his friends took him to a hospital because he was acting “erratically,” prosecutors said.

Police and firefighters discovered He’s battered body in Chu’s flooded townhome on Aug. 10 after neighbors reported water pouring out of the residence.

Prosecutors said the woman was found on her back covered in blood with a cut on her throat and “an ice pack on her throat and a small block behind her neck, supporting her head,” prosecutors said.

Police arrested Chu at the University of Washington Medical Center on Sunday after he allegedly groped a nurse’s breasts and tried “to pull her head down by hooking the back of her neck.”

Chu was arrested at the hospital where he told police he had popped two “molly” pills and smoked marijuana while with He.

Chu told cops “he thought he may have killed” his girlfriend.

The suspected killer told police he had “a memory of choking her, twisting her neck, holding her down underwater in the tub.” He said he thought he broke her neck and “remembered her bleeding from her nose.”

Chu then yanked her out of the tub and tried to revive her by bizarre means, “including sprinkling the Acai powder all over her” and “placing a ball similar to a golf ball in her mouth to fix her jaw,” documents said.

Police believe she was killed sometime between Aug. 9 and Aug. 10, when Chu left the house last.

Chu told authorities he had been dating He since January and that she had just arrived from Hawaii, where they both went to the same high school, according to KHON.

Officials said He, who is originally from China, was previously employed at the Hawaii State Capitol during the 2022 legislative session, officials said.

Chu has been charged with murder in the first degree and first degree assault for assaulting the nurse.

His bail was set at $5 million. His next court date is scheduled for Aug.28.
