Kayla Henriques, 20, pleaded guilty to manslaughter Wednesday and will serve 15 years in prison for the stabbing death of her close friend Kamisha Richards, 22, reports NY Daily News.

As previously reported by NewsOne, Henriques stabbed Richards in February 2011 after the two engaged in a Facebook feud over a $20 loan for a box of diapers.

Richards, who was dating Henriques’ brother, Ramel Henriques, loaned her friend the money for diapers but she used it on something else. In the heat of arguing over the money, Kayla claims that Richards threw her son’s milk, spilling it.

Their “beef” escalated via Facebook and text message, ultimately leading Richards to post:

“Kayla now u getin outa hand…I hope u having fun entertaining the world…Trust, IMA HAVE THE LAST LAUGH!!!”

Henriques replied, in what was clearly foreshadowing:

“We will see.”

A weary-looking Henriques, her hair unkempt and her hands cuffed, barked at reporters outside the 75th Precinct stationhouse when asked if she felt bad about the slaying. “No, ’cause it was a mistake,” she snapped. “I was protecting my kids.” … “They had been beefing for about three days,” said Barbie, a neighbor in the Cypress Hills Houses. The once-friendly pair traded Facebook insults over the weekend, with one of Kayla Henriques’ uncles saying the hard feelings were further fueled by ugly text messages. “B—h man up … I’m here make a move,” read one Facebook post from Henriques, known in the neighborhood as “KK.” “Kamisha, I miss you,” wrote Ramel Henriques, 25, on his Facebook page. “I need you baby.” Richards was a graduate of of John Jay School of Criminal Justice and was planning to attend law school in the fall of 2011, instead she died at Brookdale University Hospital. Henriques’ last Facebook post remains:
