16-year-olds Terrell Jett and William Cunningham will spend their weekend in jail, each facing a litany of adult charges including armed carjacking and robbery.
Police say it was a crime spree that rapidly totaled four victims.
"We received the first call just before 1 o'clock and then the final call came in at 1:40," said Baltimore County Cpl. Shawn Vinson.
Police say it started Thursday afternoon with the two teens carjacking a teacher at Campfield Elementary School.
The teacher told police they threatened her with what looked like a box cutter and one of them had on a Friday the 13th, “Jason” style mask.
The teens then took off in her RAV 4.
Then just a few minutes and a couple blocks later, police say Jett and Cunningham commit a street robbery.
Again, they threatened the victim with a knife and made off with his phone.
Next up was the four thousand block of Old Court Road, where police say they approached a woman sitting in her car.
The victim gave up her purse, phone and got out of the car.
The two teens then drove away in her Honda Fit when not five minutes later they use the weapons again to rob another victim and their elderly mother walking in a quiet subdivision off Old Court.
Eventually, both teens and the Honda were spotted in the parking lot of the Old Court Metro Station where they were both arrested.
If some of this sounds familiar it's because earlier this week four female teens committed much the same crime on the other side of the county.
The four girls were arrested after punching and carjacking a pregnant elementary school teacher.
Baltimore County Police are aware of the similarities.
"We have a carjacking unit, some detectives that are specialized in these types of crimes and they are looking to see if there is any connection with these,” Vinson said, “If it is a copycat crime we don't know. Information we have at this point doesn't connect these two groups at all."
Jett and Cunningham were arrested yesterday afternoon but appeared before a court commissioner just today.
The two teens will remain in jail awaiting their bail review Monday afternoon.
