All police know is the car that hit her was a green Toyota Camry. The driver never stopped, and her family is now asking for help to bring that person to justice.
Yuejuan Zhuang was simply going to the grocery store to buy the ingredients to make her grandson's favorite meal, but she never made it home. Now, her family is searching for answers.
"My mom is the person with the largest heart in the world. She cared about everyone," said her daughter, Fawn Lu.
Lu and her family are devastated, unable to comprehend how their their mom was hit and killed during a routine walk to the neighborhood grocery store.
"It's just hard to imagine any human being could do this, because at least I would expect them to stop and call 911," Lu said.
On May 27, Memorial Day weekend, the 75-year-old retired math teacher walked from the apartment, where she lived with her husband Yanbang Lu, to the nearby Welcome Grocery Store. She was hit along the 6500 block of Ranchester.
The couple always walked together. But this one time, Yanbang Lu decided to stay home to prepare for their planned trip to China.
"If we had walked together, this would never have happened," he told us in Chinese.
Adding to the tragedy, the family is upset that an initial public release of the crash by Houston police shows it happening at 7:45pm, not 3:15pm. Now they are worried, as any misinformation will make the already daunting task of finding the driver even more difficult.
"We just don't know with all the wrong information, how can they find the witness and give my mom justice?" Fawn Lu said.
The family was supposed to celebrate Yuejuan's 76th birthday this month, and her 50th marriage anniversary later this year. Now, it is asking anyone who may have seen the incident or a suspect to call police.
So far, no reliable witnesses have come forward and detectives are still looking for surveillance cameras that might have captured the car on video.
