PLAQUEMINE — Investigators on Monday were still piecing together details surrounding the fatal shooting of a 17-year-old male who was with a group of people trying to rob some gamblers outside a mobile home on Super Bowl night, authorities said.

No arrests were been made as of Monday evening; the teen was killed by one of the targeted gamblers who had pulled a gun during the robbery attempt, said Iberville Parish Sheriff Brett Stassi.

"This is a very complicated case," Iberville Parish Sheriff Brett Stassi said Monday. "But arrests are imminent."

As of Monday night, the names of the teen and the others involved had not been released. Stassi said that information would likely be made public on Tuesday. 

The fatal shooting occurred around 7:30 p.m. Sunday on Castro Street in Plaquemine. 

Stassi said the teen was at the mobile home gambling with a group of other individuals ranging in age from 16 to 20. 

The sheriff says the teen and some of the others left the scene angry after losing money in a dice game and then returned later with guns, attempting to rob the people who were still at the residence playing dice.  

"An altercation occurred, another person there drew a weapon and the young man was killed at the scene," the sheriff said. 

Stassi said his detectives spent much of Monday interviewing as many as 10 witnesses and combed parts of the levee looking for evidence. He expects the initial investigation to wrap up early Tuesday.
