A Jefferson Parish judge on Wednesday (April 29) found Jamal Harris guilty of murdering a Marrero woman and her father after her dating app meeting turned bad. 

Harris, 41, who also used the name Jarmaal Harris, is guilty as charged of two counts of second-degree murder in the deaths of Jessica Troulliet, 35, and her father, Robert Templet, 56, on Oct. 3, 2020. 

A convicted felon who was on parole when he committed the murders, Harris met Troulliet at her Marrero home after they connected through a dating app. Troulliet was not impressed with Harris’ looks, and so she wanted to end the date as soon as it began. 

Templet joined his daughter as she gave Harris a ride to Marrero. From the back seat of Troulliet’s Mercury Mountaineer, Harris shot the woman and her father in the backs of their heads. A driver passing the parked Mercury Moutaineer called 911 believing the people were passed out in the vehicle at Fourth Street and Garden Road. Jefferson Parish Sheriff’s Office deputies found that the victims had been shot and died. 

“He executed two innocent people because he got his feelings hurt that he isn’t sexy,” Assistant District Attorney Taylor Somerville said in closing argument, turning to Harris. “You took away a mother to three boys, a daughter, a nanny and a granddaughter. And you took away this family’s father, pawpaw, brother and friend.”

Detectives discovered that Troulliet’s cell phone was missing. They tracked the device’s last location to a residence on Mistletoe Street in New Orleans’ Hollygrove neighborhood, where Harris’ relatives lived. The detectives further linked Harris to the murders through his cell phone communications and geo-location technology. 

A U.S. Marshals fugitive task force arrested Harris on Oct. 21, 2020, at his cousin’s residence on Center Street in Avondale. Harris initially refused to leave the residence. When arrested, task force members found an assault-style rifle in the residence. 

In addition to the murders, Harris was convicted of obstruction of justice for taking Troulliet’s cell phone to impede the investigation and two counts of being a convicted felon in possession of a firearm. Harris was prohibited from possessing firearms because of a 2007 conviction of armed robbery in Jefferson Parish. He was on parole for the armed robbery until October 2022. 

Harris waived a trial by jury, leaving it to 24th Judicial District Judge Donnie Rowan to weigh the evidence. Judge Rowan found Harris guilty of all charges and set the sentencing for May 8. 

Assistant District Attorneys Taylor Somerville and Shannon Swaim prosecuted the case.
