Man accused of killing deputy is convicted sex offender

JEFFERSON PARISH, LA (WVUE) - The man accused of killing a JPSO deputy will be extradited to Louisiana. U.S. marshals picked up 48-year-old James Darby Tuesday morning in Tuscaloosa, Ala.

Investigators believe he murdered Sgt. Tracey Marshall in front of her home on Sunday night. Her body was found in her truck on Ashley Drive on Monday morning.

Investigators said Darby and Marshal had been dating on and off since the early 2000s and had what Jefferson Parish Sheriff Newell Normand described as a tumultuous relationship. Each had filed complaints against the other in recent years, and Marshall took out a protective order against Darby.

During questioning Darby admitted to following Marshall around on Sunday, but said he didn't kill her. The sheriff said Darby's cell phone pinged at a cell tower near Marshall's home close to the time she was killed.

"Darby first said he wasn't in the area, he hadn't seen her since they broke up. He then subsequently admitted to being in the area, to being in front of the condo at the time that she was shot," Normand said. "He admits that he followed her across the Greater New Orleans Bridge, got off at Stumpf, so he's changed his stories quite a few times."

Darby was initially apprehended in Alabama because he was wanted in New Orleans for a sex registry violation.

"Darby is a convicted felon on a 1999 charge of aggravated incest and had served or was sentenced to four years in the penitentiary," Normand said.

The sheriff said Darby was known to hide that conviction from his friends, and possibly hid it from Marshall.

Normand said after investigators spoke to Darby, they secured a second-degree murder warrant. He should be brought back to Jefferson Parish shortly.
