Charlia Potts, who failed to show up after agreeing to turn herself in Tuesday evening, was arrested without incident around 4 p.m. Wednesday.
She turned herself in with the encouragement of her family and community members, Gagan said.
Police say Potts stabbed her brother, Frank Potts, around 3 p.m. Monday during an argument in their home in the 300 block of South 26th Street.
According to witnesses, Frank Potts had a telephone that Charlia Potts wanted and he wouldn't give it to her, Richmond police Sgt. Mitch Peixoto said.
Charlia Potts then allegedly "went off on him" and went for a butcher knife, knocking over her 78-year-old grandmother to get to it, Peixoto said.
Witnesses told police she stabbed her brother at least four times.
According to Peixoto, she allegedly stabbed him so hard that she bent the handle of the knife.
Frank Potts was taken to John Muir Medical Center in critical condition. His condition has since stabilized and he is expected to survive.
Charlia Potts was booked into county jail in Martinez on a no-bail warrant for attempted murder, Gagan said.
