Girlfriend-kill suspect suicide try

THE STATEN Island man charged with killing his pregnant girlfriend tried to hang himself inside his holding cell, police sources said Friday.

Keith Jackson, 43, used a long-sleeved shirt in his suicide attempt inside the 121st Precinct stationhouse on Richmond Ave. in Graniteville around 3 p.m. Thursday, sources said.

A desk officer saw what Jackson was doing and stopped him, according to sources.

Medics took him to Richmond University Medical Center for treatment, sources said.

Jackson is accused of shooting his pregnant girlfriend Bridget Shenk, 35, to death inside their secondfloor apartment on Trantor Place in Port Richmond just after midnight Thursday, cops said.

Jackson was ordered held without bail Friday after his arraignment on murder and weapons possession charges.
