"We believe that it's associated with his disagreement over the military operations," Little Rock Police Chief Stuart Thomas told The Associated Press. "At this point it appears that he specifically targeted military personnel, but there doesn't appear to be a wider conspiracy or, at this point in time, any indication that he's a part of a larger group or a conspiracy to go further."
According to a police report, Muhammad told police that he saw two uniformed U.S. soldiers in front of the recruiting office before he shot and killed Pvt. William Long, 23, and wounded Pvt. Quinton Ezeagwula, 18, while they were taking a break outside the U.S. Army recruiting station where they both worked.
Witness Lance Luplow said he came running when he heard six or seven "loud bangs."
"I come running across the street and there is a white male and a black male and they both are in Army fatigues and they're both shot real bad," Luplow said. "One of them couldn't even talk, the other one crawled inside and said, 'I can't believe this is happening.' The other guy, I mean he was so out of it -- he was just a blank stare. Just looking up at the sky."
Muhammad was arrested shortly after the shooting and he offered no resistance to authorities who stopped his vehicle, police said.
According to sources, shortly after his arrest the suspect advised police that he was going to kill as many Army personnel as possible. At the time of the shooting, the subject had 562 rounds of ammunition available, police said.
According to court records, during his interview with police, Muhammad stated "that he recently viewed a video pertaining to subversive activities which spurred him to commit this act."
When Muhammad was arrested, he was near a Walgreens drug store and another large store with hundreds of people inside as well as outside in the parking lot areas.
But authorities said he never attempted to hurt anyone at either location and directed his hostility only to the recruiting site.
When police stopped Muhammad's vehicle, the suspect allegedly advised officers that he had a bomb in the car. Bomb techs were dispatched, but no explosive devices were found.
The car, however, was loaded with a small arsenal, according to Little Rock Police documents. Officers who searched it found the ammunition, an SKS assault rifle, a Mossberg International 702 rifle with scope and laser sight, two pistols and two military books. They also found homemade gun silencers, binoculars, a lab coat and a receipt for a firearm, according to court documents.
The ammo was loaded in magazines which were found in a vest, police sources said.
Twin City Tours, a Little Rock travel company, was listed as Muhammad's employer on an arrest report.
Muhammad's father, Melvin Bledsoe, would not comment when reached by ABC News. He would only refer all questions to the Little Rock Police Department.
