Who killed Lil Wayne's father?

In many songs recorded by Lil' Wayne, such as Look At Me Now, he mentions his father's "death".

However, when Dwayne (Lil' Waynes first name) was 2 years old, his parents divorced.

Affected by this event, Dwayne decided to drop the "D" in his name (he was a junior) and say that his father was dead because he was never in Dwaynes' life.

So, Lil Waynes' father, Dwayne Carter, is still alive.
