The Latest on the fatal shooting of former NFL player Joe McKnight (all times local):
A sheriff says the man who shot ex-NFL player Joe McKnight in a road rage incident was involved in an altercation a decade ago in which he chased down and struck another driver.
Sheriff Newell Normand in a press release late Friday said in the 2006 incident a man observed a truck driving erratically.
The victim called a number on the truck and spoke to a man later identified as Ronald Gasser.
Authorities say Gasser shot McKnight on Thursday in Terrytown, a New Orleans suburb.
Gasser and the man got into a fight on the phone. Gasser followed the man to a service station, and ''began to strike him with a closed fist several times.''
Gasser drove away and the man called 911.
Investigators found Gasser and issued a misdemeanor summons for simple battery, which was later dismissed.
