GRETNA, La. – The Latest on killing of police officer and woman in Louisiana (all times local):

10:50 a.m.

An official says the suspect in the deaths of a police officer and a woman he had stopped to help has died.

Jefferson Parish Sheriff’s spokesman John Fortunato said Saturday that Sylvester Holt died late Friday at University Hospital in New Orleans.

Authorities say the 32-year-old Holt shot himself in the chest Friday evening after threatening for hours to jump off a New Orleans bridge spanning the Mississippi River.

Jefferson Parish Sheriff Newell Normand said that, during talks with authorities on the bridge, Holt admitted shooting the 26-year-old officer and a 32-year-old woman Holt had been romantically involved with. Normand said Holt had recently found out she was pregnant with her new boyfriend.

The sheriff said the officer had stopped to help the woman on his way home from work when Holt shot him in the head.

Michael Louviere (LOO’-vih-her) apparently believed he had happened upon the scene of a traffic accident.

Instead, authorities say, the 26-year-old off-duty police officer in the New Orleans suburb of Westwego came upon the aftermath of horrific domestic violence that would cost him his life.

Louviere was one of two people shot to death Friday morning in mayhem that ended with a suicidal suspect shooting himself during an hours-long standoff with police — a standoff that unfolded as he stood on the girder of a bridge high over the Mississippi River. The suspect, 32-year-old Sylvester Holt, was in critical condition late Friday.

Jefferson Parish Sheriff Newell Normand says that, during negotiations on the bridge, Holt admitted shooting his ex-girlfriend 32-year-old Simone (sih-MONE’) Veal and Louviere.
