Details, but Little Insight, on Craigslist Killing Suspect

Mr. Markoff’s wedding is now officially delayed, too: his fiancée’s family canceled the B-Street Band, hired to play Bruce Springsteen hits at the beachfront reception on Aug. 14, its lead singer said Monday.

But while Mr. Markoff’s seemingly normal life has crumbled in the week since his arrest on charges of killing one woman and robbing another at gunpoint after meeting them through Craigslist, hints have been slow to emerge as to why he might have committed the crimes.

“What has been portrayed and leaked to the media is not the Philip Markoff that I know,” said Megan McAllister, his fiancée, in a statement released Monday through her lawyer. “To me and my family, he is a loving and caring person.”

But contrary to statements she made last week, Ms. McAllister did not assert that Mr. Markoff had been “set up.”
