Police say the victims responded to a Craigslist post that offered the iPhone 5  and met Jacob Patrick Valentine in front of George Cromwell Elementary School in Glen Burnie.

In one case on Saturday, Valentine discharged a pellet from a pellet gun, missing the victim and striking his vehicle’s rearview mirror.

In another recent case, a 30-year-old male victim came forward and reported being a victim in a similar situation on July 29.

In that incident, the victim went to the elementary school to meet the seller of an iPhone from the same online advertisement when the suspect pulled out a gun and demanded the victim’s money and phone.

The victim complied and the suspect ran away.

Detectives posing as a potential buyer responded to the same Craigslist post. The suspect agreed to sell the iPhone and suggested that they meet in front of the elementary school Monday night.

At the school, Valentine approached the undercover detective and pulled out what looked like a black semi-automatic handgun in an attempt to rob him.

Additional detectives responded and the suspect tried to run away.  Valentine was then arrested,

An inspection of the handgun revealed it to be a pellet gun fashioned as a convincing replica of a semi-automatic firearm.

Detectives believe there may be additional victims.
