someone accused me of stealing their car part & threaten me..?

[Joey]

Now i posted an ad on craigslist & i bought this car part long time ago from some dude because it was dirt cheap. i bought it just to set it on the side incase if my engine was blown. I wanted to get rid of it now because i have no used of it because my car was totaled. So then this random number ask for pics & i send them pictures thru email because i didn't have picture message. & now they all telling me it's theirs and assuming that i got rest of his parts. I mean how can you tell if its yours, the part that i have are common. He was gonna threaten to get me and kill me and stuff. So then i turn off my phone, deactivate my email & facebook because my email shows my whole name & afraid he's gonna find me & hurt me. I already sold the part later that day. Now can i sue this person for accused me of stealing??
