According to police, a son shot his mother and their family pets.
Police released the victim's identity and it turns out she was a well-known figure in Houston: Reyna Rogers.
Rogers -- known affectionately to friends as "Yuki" -- made her most significant impact in the heart of Houston's Asian American community where she was a leader, and she will be missed.
"She was a fountain of energy," friend Gordon Quan said of Rogers.
A native of Japan, Rogers embraced Houston as home. Her volunteerism is legendary in the nonprofit circle, having served as the executive director of the Asian Chamber of Commerce and the International Trade Center.
"As an emerging community -- Asian Americans -- we don't have our share of socialites or philanthropists who establish themselves and are always there doing worthy causes," Quan said. "She, to me, was one of the first."
Early Thursday, Rogers' 26-year-old son shot her at least eight times inside their townhome in southwest Houston. Police say he used an assault rifle and had more weapons nearby.
The former military man is believed to have bouts with Post-Traumatic Stress Disorder (PTSD). He was hiding in an upstairs bedroom when authorities arrived and arrested him for murder. He was being held Saturday night on $50,000 bond.
Police are now trying to figure out what triggered such a violent domestic dispute, even speaking with Rogers' other son, who was able to run out of the house during the shooting.
Rogers' closest friends describe her generosity as unmatched.
"I miss her, being gone, because I miss her spirit," friend Atif Bhanjee said.
Her hallmark of connecting Houston's growing Asian community will live beyond her time in this corner of our city.
Houston won't be the same for us," Bhanjee said. "She brought us together."
