Chilling footage shows woman walking with boyfriend moments before he allegedly killed her

Footage of a young couple walking home with groceries has taken a chilling significance after the boyfriend was accused of killing his partner shortly afterwards.

A young woman was found dead in her boyfriend’s condo after neighbors reported water pouring from the residence.

When officers arrived at the townhome on August 10, they may not have expected the gruesome sight just behind the bathroom door.

Zoey Suyun He, originally from China and who lived in Hawaii, was visiting her boyfriend, Andy Chu, between August 9 and 10.

Officials found He on her back, covered in blood with a cut throat and ‘an ice pack on her throat and a small block behind her neck, supporting her head’, according to prosecutors.

According to KOMO News, the autopsy would show that she suffered from blunt force trauma to her neck, face, chest and limps, as well as having a golf ball lodged inside of her throat.

Chu, 26, and He attended the same school, according to KHON and had been dating since January this year.

The couple had been out to buy groceries on the day of her murder, and surveillance footage caught the pair bringing bags into the Lake City, Seattle, home.

However, it also caught something else and it’s chilling.

A neighbors’ security camera showed Chu leaving his home the very next day, wearing the same clothes and hiding something underneath his shirt.

With no sign of He, Chu removed the item, which appeared to be wrapped in a towel, and walked out of view of the camera, Fox 13 reported.

Prosecutors would later say he began acting ‘erratically’ that same day and friends took him to a hospital.

He was then arrested by police at the University of Washington Medical Center after he allegedly groped a nurse’s breasts and tried ‘to pull her head down by hooking the back of her neck.’

Following his arrest, Chu said 'he thought he may have killed' his girlfriend, according to the King County Prosecuting Attorney’s Office.

The man told police he had popped two ‘molly’ pills and smoked marijuana while with He and admitted to having ‘a memory of choking her, twisting her neck, holding her down underwater in the tub'.

Revealing that he believed he had broken her neck and ‘remembered her bleeding from her nose’, Chu then allegedly dragged her out of the tub and tried to bring her back to life using strange strategies.

Apparently, he thought he could revive her by ‘sprinkling the Acai powder all over her’ and ‘placing a ball similar to a golf ball in her mouth to fix her jaw’.

It’s not known why He was visiting that weekend specifically, however there is a Chinese holiday around the date of the murder, which is similar to valentine’s day, called the Qixi Festival.

Charges of first-degree murder and felony assault were put forward against Chu in court this week.

According to KHON, his bail is currently set at $5 million with Casey McNerthney, a spokesperson for the King County Prosecuting Attorney's Office sharing that the amount is related to his risk of leaving the country.

He said: "Anytime you have somebody charged with murder there's a concern of flight risk despite their connections showing that to the court is an argument, so that is an element.”
