(AP/WJLA) — An ex-Marine from Virginia accused of firing shots at the Pentagon and other military targets waived his probably cause hearing Thursday, meaning the courts have found there was enough evidence to justify his arrest.

Yonathan Melaku, 23, will remain detained until his next court appearance.

Authorities say they have evidence linking him to a series of overnight shootings in October 2010 at not only the Pentagon but also the Marine Corps museum in Quantico and other military targets.

Melaku was arrested and charged in June when he was spotted after dark in Arlington National Cemetery with a backpack containing potential explosives material and notations referring to jihad and Osama bin Laden.

That arrest set off a massive security scare in and around the Pentagon.

In October, Melaku pleaded guilty to larceny charges in Leesburg that were unrelated to the Pentagon incident. He's also accused of trying to escape from a Loudoun County jail.
