Dwayne Lebarr Jr., police say, strangled and beat his older lover to death inside a North Bay Village apartment, and later drove to a UPS packaging store to do something even more unexpected.

He mailed himself the key evidence.

According to a newly released court documents, Lebarr sent himself a package containing the bloody clothes detectives believe he wore last month when he allegedly killed Craig Douglas Wolfe, 63.

Detectives intercepted the package, which also contained a laptop police believe Lebarr stole from Wolfe.

The blood-stained clothes and electronics, also including a camera police believe he bought with Wolfe’s money, are now crucial evidence in the murder case against Lebarr.

But Lebarr, 18, is a fugitive and is believed to be hiding somewhere in South Florida.
