JACKSONVILLE, Florida (AP) — A jury has found a man guilty of first-degree murder for fatally shooting a teenager after an argument over loud music outside a Florida convenience store.

The jury reached its verdict Wednesday after more than five hours of deliberations.

Prosecutors say Michael Dunn shot with intent to kill when he fired 10 times into a vehicle carrying 17-year-old Jordan Davis and three of his friends in November 2012.

Dunn testified that he thought his life was in danger.

Dunn was convicted previously of three counts of attempted second-degree murder in February and already faces at least 60 years in prison.

The jury in the first trial deadlocked on the first-degree murder count, which led prosecutors to retry him in this case.
