A dispute between the two friends began over $20, money that had been given to buy baby formula and diapers, but that went for some other purpose. Days later, it became a heated public matter, splayed on the two young women’s facebook Page.
At 5:44 p.m. on Sunday, one of them, Kamisha Richards, 22, wrote that this would be “the last time u will con me into giving u money.†Ten minutes later, the other, Kayla Henriques, 18, replied, “Dnt try to expose me mama but I’m not tha type to thug it ova facebook see u wen u get frm wrk.â€
The war of words escalated over Facebook. In capital letters, at 8:52 p.m., Ms. Richards said that she would have the last laugh. Ms. Henriques replied within seconds: “We will see.â€
They exchanged more messages, until about 9:30 p.m. on Sunday.
About 24 hours after their last Facebook exchange, Ms. Richards was dead, killed by a kitchen knife to the chest delivered inside an apartment in East New York, Brooklyn — according to the police, the home of Ms. Henriques, Ms. Richards and relatives of both women, including Ms. Henriques’s brother, who was dating Ms. Richards.
By about 1:30 a.m. on Tuesday, Ms. Henriques had been arrested, after witnesses helped point investigators in her direction, and the suspect “said things to implicate herself,†according to a law enforcement official. “It was witnessed by several people, in the apartment,†the official said.
In retrospect, some of the clues were spread like electronic bread crumbs for anyone to see.
Ms. Henriques was charged with second-degree murder and criminal possession of a weapon, said a spokesman for the Brooklyn district attorney’s office.
