The trio invaded the home at 5 a.m. and took Carmen Brady at gunpoint when they couldn't find her brother, the apparent target of the abduction, according to NBC News.
In exchange for her safe return, the kidnappers -- who are now in custody -- demanded $10,000. They fled in a Buick belonging to Brady's father.
The home that was broken into is a "known drug house," NBC Philadelphia reported.
The thieves also stole two iPhones during the invasion, according to the Philadelphia Inquirer.
Police haven't revealed yet how they tracked Brady to another residential house. They told the Inquirer that suspects have been apprehended.
