Pennsylvania is making it harder for criminals to get their hands on guns.
On Friday, Gov. Tom Corbett signed the "Brad Fox Law," named after the Plymouth Twp., Montgomery Co., police officer killed in the line of duty four months ago.
"It's a good bill to keep Brad's memory alive," said Kathy Fox, Brad's mother.
Fighting back tears, Kathy and Lynsay Fox now know Brad will never be forgotten. With the stroke of a pen, the new law will forever carry the name of the fallen police officer.
"It is time we held others accountable in his name," said Corbett. "If you pass along a firearm to a convicted felon, you will join the ranks of that convicted felon, and see the inside of a prison if convicted in Pennsylvania."
Surrounded by officers, the family of Brad Fox and Fox's K-9 partner Nick, Corbett ceremonially signed the new bill.
"It's an honor to be able to share this with my kids one day, and know this happened because of their dad," said Lynsay Fox, Brad's wife, who is pregnant with their second child. Their baby boy is due in March.
The law intends to go after straw purchasers, creating harsher penalties to prosecute the people supplying felons with guns. It creates a five-year mandatory minimum sentence for repeat offenders.
"It's an important bill for law enforcement because it will give us a significant and appropriate sentence through straw purchases of firearms," said Montgomery County District Attorney Risa Vetri Ferman.
"Hopefully, this will just help someone, prevent someone else from going through this tragedy," said Kathy Fox.
In September, Fox was ambushed and shot in the head by a felon. Investigators said his killer obtained the murder weapon through a straw purchase.
American flags outline a memorial honoring Fox at the site he was killed in Plymouth Township. He was the first officer in the Plymouth Township Police Department killed in the line of duty.
"With the signing of this today, hopefully it will prevent this from happening again," said Chief Joseph Lawrence, Plymouth Township Police Dept.
Fox's family said it's an honor and needed to be done.
