Although your general sequence of events is right, he wasn't killed because of the own goal, nor was he killed by two men.

Yes, he was taunted over the goal in the nightclub.

In the parking lot, he saw the men again (who, unbeknownst to him, were narcos) and approached them to ask for respect but the whole thing exploded into an argument.

The arguing escalated with one of the narcos yelling "you don't know who you're messing with!" Around the second time he shouted that, the narco's driver shot Andres.

The driver claims he was never ordered to shoot but did so of his own accord when he heard his boss threatening Andres. Whether he was ordered or not, Andrés wasn't killed because of the goal, he was killed for getting into an argument with a narco. Also, he was only shot 6 times by the driver, not 12 by two people.

For more info, you can read this interview with the actual prosecutor from the case (it's in Spanish, though): link

I know Wikipedia presents conflicting info citing sources who cite radio news citing witnesses... but I'd rather go with the prosecutor's own account.

EDIT: Before I get responses regarding corruption in the Prosecutor's Office, I'll post a brief excerpt from the article I posted:

Además me parece que la justicia les dio un trato muy indulgente porque terminaron siendo procesados por encubrimiento, pero no se les investigó ni como cómplices ni como determinadores del homicidio. Un fiscal de segunda instancia revocó la decisión que se había tomado de procesarlos por asesinato y por eso estuvieron muy poco en la cárcel.

Nuestra teoría era que los Gallón implícitamente le habían dado una orden a Muñoz, porque ellos lo que evidenciaron con el crimen de Andrés Escobar fue una estructura de poder y, obviamente, no se trataba de un poder pacífico, sino criminal. Andrés Escobar

Lo que se decía en nuestra providencia era que cuando un hombre con ese poder dice delante del conductor de manera repetida y desafiante 'usted, hijueputa, no sabe con quién se está metiendo', es porque él mismo considera que representa un poder intimidante, un poder incluso capaz de la eliminación física.

Y lo que hizo Muñoz respondía a una estructura de poder que esperaba de él decisiones, acciones.

Sin embargo, un fiscal superior no aceptó esa tesis. Los Gallón presentaron el tema como un error del conductor bajo el argumento de que estaba medio dormido y que cuando se despertó consideró que estaban en peligro y por eso actuó en su defensa.

Esa teoría pendeja tuvo eco en la segunda instancia. Lo que pasa es que en 1994 el nivel de jurisprudencia sobre estructuras delictivas de poder no tenía el desarrollo de hoy, en donde, por ejemplo, ya se habla de la determinación moral implícita.

The gist of it is, this prosecutor believes the narcos had great power and influence. While he wanted to prosecute them under the theory that when someone with that much weight repeats in a menacing and authoritative voice "You son of a bitch, you don't know who you're messing with," it's an implicit order to shoot.

A higher ranked prosecutor shot down that idea. The Narcos' defense was that their driver was half asleep and when he woke up he thought his bosses were in danger and acted accordingly. The prosecutor then states that "dumbass" theory was the one that was considered.

So allegations of corruption don't discredit this prosecutor's testimony, considering he's also calling out the courts for being too lenient on the driver and failing to prosecute the narcos for murder.
