Police and reporters are slowly piecing together the story behind the double-stabbing and suicide attempt that snarled mass transit this morning. The 31-year-old alleged assailant, Ryan Devaney, had a history of fighting with his parents according to neighbors, had been "in and out of institutions" and often fought loudly with his family.

This morning something went terribly wrong in the home of Devaney's parents, Margaret and Raymond Devaney. Around 8:15 a.m. the couple's son, who had recently moved out of the house, flew into a rage and stabbed his 57-year-old mother in the eye and abdomen before slashing his 50-year-old father's throat. "The father stumbled out of the home, holding his blood-soaked neck while his son ran from the home en route to the F and G station in nearby Bartel Pritchard Square."

Sanitation workers and neighbors quickly ran to assist the older Devaneys until paramedics arrived. The son, meanwhile, jumped in front of a Queens-bound G train. “He attacked his parents, but was so distraught over what he did that he tried to take his own life,” an NYPD source told the Brooklyn Paper.

Margaret Daveney was declared dead on arrival at New York Methodist Hospital while her husband is listed in critical condition. Their son's suicide attempt, meanwhile, appears to have been just that. He is currently listed as being in serious condition at Lutheran Medical Center.

Ryan Devaney had previously been arrested two years ago, in Palm Beach, Florida, for possession of drug paraphernalia. You can read some of our readers descriptions of the scene in the station here.
