The CBS procedural has tapped Brooklyn Silzer to play Lucy, the daughter of married CSIs Danny (Carmine Giovinazzo

) and Lindsay (Anna Belknap). Silzer, who has also played Robin and Patrick's daughter Emma on General Hospital, will appear in the new season's fourth episode. Lucy was previously played by twins Nadia and Talia Hartounian.While many fans welcome any chance they get to see the Messer family together, this episode may not be such a happy occasion. While attending a campaign rally for Senator Grant Hamilton (guest star Neal McDonough), the family lands in the middle of a shootout, which injures both Lindsay and the senator. We hope little Lucy is OK!

Given Silzer's casting, it's possible viewers will see more of Lucy this season. Executive producer Pam Veasey recently told that the new season will take a closer look at all of the CSIs outside of work.Season 9 of CSI: NY kicks off Friday, Sept. 28 at 8/7c on CBS. Silzer's episode is expected to air some time in late October.
