Investigators probing Mel Gibson for domestic violence are looking at a secret email he sent ex-lover Oksana Grigorieva to determine if it provides an explanation for the actor’s erratic behavior.
In the email, sent the day after an explosive January 6 confrontation with his one-time lover, the Lethal Weapon star wrote: “The tranqullizers (sic) only make me nuts.”
It was an apparent reference to pharmaceutical drug use.

Tranquilizers are depressant drugs that are used in the treatment of anxiety, insomnia — and sometimes during alcohol withdrawal.
The written correspondence is yet more damning evidence in the domestic-abuse probes against the embattled star.
The message could also shed new light on the psychological state of the Oscar-winning director and deliver an insight into what could have caused his angry outbursts against his gal pal.
Mel sent the explanatory note to Oksana from his iPhone on January 7 at 9:39am.
The night before, Oksana has claimed, Mel punched her in the face twice and then tried to choke her while she was holding their infant daughter Lucia, who was only two-months-old at the time.
Breaking Celebrity News first broke the story -- with world exclusive photographs -- that Oksana's mouth and teeth were badly damaged.
She says it is from Mel punching her during an explosive argument at the superstar's Malibu home.
