Serena learned just before Konta loss that half-sister's killer had been freed

By BBC Online

Serena Williams says she discovered just minutes before her match against Johanna Konta last month that the man convicted of killing her half-sister had been released on parole.
Briton Konta inflicted the worst defeat of Williams' career by winning 6-1 6-0 in the first round of the Silicon Valley Classic in San Jose.
Williams' elder half-sister Yetunde Price was shot dead in 2003 aged 31.
"I couldn't shake it out of my mind," said the 23-time Grand Slam champion.
Robert Maxfield was jailed for 15 years in April 2006 and Williams, 36, attended the sentencing.
She told Time magazine: "No matter what, my sister is not coming back for good behaviour."
Price was shot dead in Compton, Los Angeles. Her children were 11, nine and five at the time.
