What we know:

HOUSTON - Dawud Parker, 44, has been arrested and charged with the murder of his sister, 48-year-old Alisha Parker. 

The shooting happened at 1206 Barker Cypress Road just after 9 p.m. on Tuesday. Houston Police said they responded to a shooting at a gas station and found Alisha Parker unresponsive with multiple gunshot wounds in the driver's seat of a black BMW sedan. She was pronounced dead at the scene.

Parker was arrested on February 6th. He provided a statement to homicide detectives and was booked into the Harris County Jail. 

What they're saying:

A close friend, Crystal Beasley, said she met Alisha Parker while they were in prison. Beasley said they were so close, they considered each other sisters. 

"I have witnessed him and Alisha have many arguments. However, Alisha, her words are her punches. So I can see her saying something to him that provoked him," said Beasley. 

Beasley describes Alisha as a funny, smart, and religious woman who always helped her family in a time of need. 

"Her brother and her sister, and her son, she helped them. Girl would do anything to make sure they were clothed, they were fed, and they were housed. Anything. And that’s what I don’t understand. You bit the hand that fed you," said Beasley. 

What's next:

A judge set Dawud Parker's bond at $500,000.
