When the mother broke free, ran outside and called 911, the teenagers fled.
Their freedom was short-lived.
Only about 150 yards from the women's home, police found the suspects, Daniel K. Walston and Alexander W. Granger, at Granger's home, Chester County District Attorney Thomas Hogan said in a news release.
Walston, 17, of the 200 block of Glenrose Road, Coatesville, and Granger, 18, of the 1300 block of Fieldpoint Drive, Birmingham Township, were arrested and charged with robbery, burglary, conspiracy - all felonies - and related offenses.
Walston was "defiant and uncooperative with the police," Hogan said, and "due to the nature of the crimes, he is charged as an adult."
They were arraigned, and after failing to post $75,000 cash bail, were sent to Chester County Prison.
An affidavit of probable cause gave the following account:
Granger confessed that after breaking a first-floor window at a home in the 600 block of General Weedon Drive, he and Walston collected an undetermined number of .357 magnum pistols, TVs, computers and other items.
"They put them in a trash can at the residence and then wheeled those items back to his Fieldpoint Drive residence;" left them in the basement with the trash can, and went back for more, each armed with a stolen .357.
While they were again inside the burgled home, Granger said the two women entered. Walston "pointed a .357 magnum pistol" at one of the women. Granger said that while he "had a stolen .357 magnum pistol in his pocket," he could not remember if he drew it.
After getting permission from Granger's mother to search the Granger home, police found the loot.
