In addition to the extreme bruising and blood on his right hand and body, police noticed that Chen’s sandals, found in the hallway, were also covered in blood.

Chen, who was initially taken to a hospital, remains in custody awaiting an arraignment on Wednesday.

He and Yu bought their home at 714 Valley Way last spring in April for $2.05 million, according to property records.

The two-story home, freshly painted with a manicured lawn and shrubs, is located in a quiet residential neighborhood in Silicon Valley.

A silver BMW SUV was parked Monday in the driveway of the now-closed home, which was already packed with crime scene investigators last Tuesday when they arrived in the morning and stayed into the night.

“That’s my bedroom window right there,” neighbor Jenny Powell, 43, told DailyMail.com. ‘I am shocked. This was all happening and I had no idea.”

Powell said Chen and his wife had lived there since April of last year with a cat named Cooper and that they seemed friendly and brought her cookies and a card when they moved in.

But the couple mainly kept to themselves. When Powell’s son heard about the murder, he said to his mother, “You mean the locks next door?”

“They weren’t here long and didn’t have much contact with people,” Powell said.

She described the bizarre scene where a dozen police cars flooded her block and a CSI truck was parked in front of her house all day.

Another neighbor, Sylivia Atondo, told DailyMail.com that she had only seen the couple walking down the street a few times.

“They seemed friendly when we saw them, nothing special,” she said.

She said her neighborhood is close-knit and has a lot of gossip, so “whenever there was an argument involving neighbors, people around here would talk about it. But there was nothing. That’s why the neighbors are completely shocked.’

Google spokesperson Bailey Tomson told The New York Post in a statement: “We are shocked and deeply saddened by what happened to Xuanyi.

‘Our thoughts are with her family at this time and we will do our best to provide support to them and colleagues as they cope with this tragic news.’

According to his Linkedin, Chen worked on the YouTube short algorithm for Google, while Yu’s page says she was a software engineer.

Both studied in China at Tsinghua University and the University of California San Diego.
