The terrorist who killed at least 10 people when he plowed his truck down crowded Bourbon Street in New Orleans was an American-born military veteran who was living in a run-down trailer park where he kept sheep and goats in the yard — just blocks away from the local mosque.

Authorities say Shamsud Din Jabbar, 42, from Houston, had an ISIS flag strapped to the rented Ford F-150 Lightning EV truck he used to carry out an act of premeditated terror on New Year’s Day.

In a YouTube video he posted in 2020 for his real estate business, a clean-cut Jabbar described himself as a reliable, trustworthy native Texan who spent 10 years in the military, which taught him “the meaning of great service.” But later, Jabbar lived in a squalid trailer park on the outskirts of Houston that is home to mostly Muslim immigrants.

Geese, chickens, and sheep roamed freely in Jabbar’s yard when The Post visited hours after the attack.

One neighbor told The Post she spoke only Urdu, Pakistan’s national language.

The neighborhood is also within walking distance of the local mosque, Masjid Bilal — where no one answered the telephone on Wednesday.

Law enforcement sources told The Post that they found videos Jabbar made where he referenced the Quran — Islam’s holy text.
