(NEWS CENTER) -- The parents of a Virginia TV reporter shot to death on live television are in Maine to push for Yes on Question 3.

If approved, the initiative would close loopholes in state law by expanding background checks to include all gun sales and transfers.

Alison Parker and her cameraman were killed after a disgruntled former employee opened fire during a live report in August of last year.

Since the shooting, Alison's parents have committed themselves to enacting tougher gun control laws.
The couple is the latest in a string of high profile family members and victims of gun violence who have come to Maine to lobby for expanded background checks.

Barbara and Andy Parker say they were invited to come to Maine by supporters of Question 3.

The couple says they didn't see their 24-year old daughter die on live television - but the world as they knew it ended.

Parker spoke out against gun violence on national television the day after his daughter died as a way to channel his grief and anger he says into "action."

Since their daughter's horrific death the Parkers have traveled across the country waging a campaign for gun control -- they say Question 3 which would expand background checks to private gun sales in Maine will save lives.

'When you have reasonable gun laws in place, where you close loop holes, universal background checks-- gun violence goes down," said Parker.

The couple plans to meet with volunteers with the Yes on Question 3 campaign this weekend and meet with Julie and Wayne Richardson, whose daughter Darien died after being shot by an intruder.
