Is the parent liable for windshield broken by his kid?

Sorry I have to use English - don't have Chinese input software.  Had a bad day and hope the nice people here can help me out:  A kid threw a rock and cracked my windshield while I drove by a football practice field this evening.  He was 7 yo.  His dad did come forward and gave me his name phone # and email.  There were other adults on the football field at the time.  I called police and the policeman took down the father's name and address, kid's name and birthday.  I gave my name, phone and address, driver license, insurance info.  My question is: Is the father liable for my windshield repair cost?  If he refuses to pay, I might have to go after the football club through their liability insurance.  Unfortunately I don't have comprehensive insurance coverage for my car.:(  I'd appreciate any advice.
