10. SOUNDBITE (English) Rohan Hepkins, Mayor of Yeadon:

"Drugs, drugs, weapons charges. Drugs and a lot of other petty crimes but he has a long rap sheet. (Reporter: Did he just get out of prison?) I believe he just got out of prison, as well. (Reporter: OK, and uh, did you guys ever think that he may have been a radicalized Muslim?) That's a complete shock to me and for this small borough to, you know, think that we may have been harboring, not just a criminal but a potential terrorist; you see that on TV nationally but you never think that it would hit your small town. So as mayor, it's totally shocking to me and it just shows that this can happen anywhere."

The FBI and other law enforcement agencies combed through Valerie Holliday's home Friday, whose son Edward Archer confessed to shooting a Philadelphia officer.

Jesse Hartnett was slowly patrolling his usual West Philadelphia beat Thursday just before midnight when Archer appeared out of the darkness, firing a hail of bullets at close range as he charged toward his vehicle.

Hours later, police say, Archer confessed and told investigators he was following Allah, and had pledged his allegiance to the Islamic State group. Archer said he believed the police department defends laws that are contrary to Islam, police said.

Local and federal authorities spent much of earlier Friday trying to verify the motive and executing search warrants at two Philadelphia area properties associated with Archer, hoping for more insight into how and why the shooting happened.

Archer's mother told The Philadelphia Inquirer her 30-year-old son had been hearing voices recently and had felt targeted by police. She said the family had asked him to get help and described him as a devout Muslim.

Investigators believe Archer traveled to Saudi Arabia in 2011 and to Egypt in 2012, FBI special agent Eric Ruona said, and the purpose of that travel was being investigated by the FBI.

Police said there was no indication anyone else was involved, and it is unclear if and where Archer practiced his faith locally.
