( CNN ) -- The Facebook photo , grainy and blurred , shows a boy in his Cub Scout uniform standing in the sun on the side of the road , his right arm in a stiff salute as cars pass by in Woodlawn , Virginia . The caption tells the rest of the story . Nine-year-old Lane Snow salutes the two-mile funeral procession Thursday for Virginia State Police Trooper Andrew Fox . The trooper , a graduate of Virginia Tech , was run over and killed while directing traffic at the state fair earlier this month . When the photo landed in Virginia Tech police Lt. George Jackson 's inbox , he knew it would be a hit . Jackson manages the social media accounts for the college police department and posted the photo Friday in two places on the department 's Facebook page . He asked fans to share the photo `` and see how many likes we can get for this young Boy Scout and his tribute to Trooper Fox ! '' The first day , the image of Lane Snow 's salute received 15,000 shares . The next day it had 45,000 . By Tuesday it had been shared more than 68,000 times and growing , reaching an estimated 4 million people , according to Facebook 's own analytics , Jackson told CNN . He had no explanation for the numbers of shares except to say the comments reveal a community who supported Snow 's character . Lane Snow did n't know trooper Fox , but he told local station WDBJ7 he did it because `` I was sorry that Andrew Fox died . '' Snow 's parents told the station he came up with the idea to dress in uniform and salute the procession on his own . Everyone who saw it was touched , including Fox 's widow , who saw Snow saluting as her car passed , WDBJ reported . It was a pure and touching gesture , Jackson said . In an interview with CNN , Jackson said he wanted to bring awareness and attention to the state police and Fox 's family as a measure of support . `` I just remembered how it felt to have lost an officer . The community rallied around us , '' Jackson said . At Snow 's Cub Scout meeting Monday night , 10 officers from various agencies -- some of whom knew Fox personally -- showed up to thank Snow in person , said Cub Master Darrell Lineberry . Lane Snow told the local station that he wants to be a policeman when he grows up , `` just like Andrew Fox . ''
