OT Lawyers: What are my protection options as a witness.

Backstory: 4 years ago I witnessed an accident in which a man died. He was run over by a trailer driven by the man who was dating his ex wife. Dude on the bike was in a local biker gang who deals in weapons and drugs. It was a complete accident. The man on the bike swerved at the truck, causing the truck to dive away into the right lane(4lane road). When he dove right, the back end of the car trailer swerved left, as it did this the man on the bike lost control , laid down his bike, then the trailer went over his head.

Today I was contacted by someone claiming to be the dead man's daughter. She claimed to have the police report and started accusing me of taking money to give a statement which lauded the innocence of the man driving the truck. She then implied that this wasn't over, and that I'm as guilty as the "killer" who kept out of jail. Also kept.him from losing everything in a wrongful death lawsuit.

I told her nothing, and simply said my deposition and police report would suffice to answer any questions she had.

I don't know what to do. Do I load up on ammo? Do I contact the defense attorney who handled the case? Do I just leave it and ignore it? Call the police department and ask why my information was given out to apparently anyone who wanted it? Help.
