Woman stalked, killed in alleged domestic violence case in Bristol Township, police say

BRISTOL TWP., Pa. (WPVI) -- A Philadelphia man has been arrested for murder in what the Bucks County District Attorney is calling a case of domestic violence in Bristol Township, Pennsylvania.

Yujun Ren, 32, is being charged with criminal homicide, possession of an instrument of crime, and stalking.

Bristol Township police say he arrived with his attorney to turn himself in around 12:30 p.m. on Sunday.

Police say Ren led them to a home on the unit block of Outlook Lane in Levittown, where they found a woman with a gunshot wound to the head sitting in the driver's seat of a car.

The victim was pronounced dead on the scene. She has been identified as Yuan Yuan Lu.

"We're still processing a lot of it. It still doesn't feel real," said Lu's cousin, Natalie Truong.

"All we know is that there was some kind of domestic relationship," said Sgt. Jason Mancuso with the Bristol Township Police Department. "We believe the couple resided in Philadelphia, and at some point, the relationship had taken a turn for the worst and the victim had come back to her residence in Bucks County."

In a statement, Bucks County District Attorney Joe Khan said their investigation revealed a "chilling course of conduct."

According to court documents, on Saturday night, just hours before she was killed, Lu went to Philadelphia police to report the sexual assault.

Truong said Lu confided in her about the abusive relationship last week and she convinced Lu to file a report.

"All she wanted to do was leave. Just to leave him," Truong said, adding that they dated for nearly a year.

Court documents reference a recorded interview where she told detectives Ren sexually assaulted her earlier that day at his South Philly home. She stated she decided to end the relationship, packed her belongings, and blocked him. She also mentioned she was afraid of him, and he carried a gun everywhere.

Evidence shows Ren began stalking her vehicle early Sunday morning before fatally shooting her. In Ring camera video captured around 5:45 a.m., you can see the victim driving by. Trailing behind her is the car police described as the suspect's.

Then, around 12:30 p.m., detectives found Lu shot to death in her car.

"It's tragic. She was trying to get out. She was trying to do the right thing," neighbor Dan Bogan said.

According to court documents, Ren told police he was standing outside of her car door when Lu "said hurtful things and took their cats and dogs, so he took a gun out of his waistband to scare her and the gun discharged."

Ren was arraigned Sunday night and denied bail.

Truong hopes her kind cousin who always saw the good in people gets the justice she deserves.

"I want them to remember her as a really happy, strong girl. I don't want them to see her as a victim because she wouldn't want to be seen like that," she said.

Another neighbor, Kelly Wallin, remembered Lu as warm and kind.

"She always said 'Hi. Good morning. Your children are beautiful. Have a good day.' Very sweet," Wallin said.

Lu's family is raising money for funeral expenses and to help bring relatives from China to the area.
