According to reports, Henry - who authorities say was inspired by ISIS - left his Germantown job on Tuesday, March 26 and then allegedly stole a U-Haul van that he meant to use in his terror attack at the National Harbor.
Rondell Henry, 28, from Germantown, was arrested on March 28 at the Waterfront complex in Prince George's County, Maryland. His family, anxious about his well being, reported him missing to police who then released his photo with a missing persons report.
Henry could not breach the airport security area and after two hours drove to the National Harbor, prosecutors said. At that point, Henry allegedly drove the U-Haul to the National Harbor in Maryland, arriving around 10:00 a.m. on Wednesday, March 27.
He is now charged with transporting a stolen vehicle, but no terrorism-related counts yet.
Prosecutors filed a motion Monday to hold Henry in jail pending trial, claiming he is "a flight risk and a danger to the community".
"For two years, the defendant has harbored "hatred" (in his words) for 'disbelievers" who do not practice the Muslim faith, ' prosecutors wrote in their motion.
"But so early in the morning on a weekday", prosecutors wrote, "the defendant did not find the sizable crowd upon which he desired to inflict his radical conduct".
Authorities said they found Henry's cellphone that he had tossed along an interstate highway. Police found the vehicle parked a few spaces away from where the U-Haul was stolen.
Police at the scene where a man hit pedestrians then flipped the U-Haul truck he was driving in Edmonton, Alberta, Canada.
Henry is set to appear in court for a detention hearing on Tuesday.
A spokesman for the Baltimore field office of the FBI says investigators are expected to provide more information after Henry's court appearance on Tuesday.
According to the complaint, Alexandria Police Department was contacted about a leased U-Haul vehicle that had been stolen at the mall in Alexandria, Virginia.
If Henry is convicted he faces a maximum sentence of 10 years in prison for interstate transportation of a stolen vehicle, according to prosecutors. Henry reportedly told United States officers he was "just going to keep driving and driving and driving" and didn't plan on stopping.
Federal public defender Michael CitaraManis argued that the government "is trying to fit certain facts into their narrative" that Henry meant to carry out a terrorist attack last month at the National Harbor, a popular waterfront destination just outside the nation's capital.
