skylar had planned to mark together. you two should be doing everything alongside each other. >> yeah. they didn't just take away a bride. they took away a bridesmaid. >> skylar's second parents say they'll miss out too. >> when morgan walks down the aisle, skylar won't be there. >> she will be. >> she'll be watching over her? >> she will. >> in june 2013, dave and mary had a memorial service at the site where skylar was killed and they're proud to have helped pass skylar's law, which requires amber alerts even when police suspect a teen has run away. a national version of skylar's law is currently making its way through congress. it's peaceful here now. they come here often, even in the winter, to tend the small garden they've built for skylar. >> mary, how do you want skylar to be remembered?
