Nick Lashaway, who guest starred in a Season 2 episode of HBO’s “Girls,” died in a car accident on May 8, and Lena Dunham paid tribute to the actor in a Wednesday Instagram post.

“Just heard the incredibly sad news that Nick Lashaway was killed in a car accident on May 8th. Nick was such a talented, funny and kind person and we were so lucky to have him as a part of our ‘Girls’ family when he played Frank in episode 207,” the post reads. “We will always remember the week we shared with him, his playful smile, his easy instincts, how much he made us laugh even when we had to stay up all night in the woods. We are sending love to his family and friends and feeling such gratitude for his gifts. RIP sweet Nick.”

Lashaway played Frank, the teenage son of Jessa’s (Jemima Kirke) estranged father and Hannah’s (Dunham) brief love interest, in the 2013 “Girls” guest spot. Beyond that role, he appeared in films such as “The 40-Year-Old Virgin” (2005), “The Last Song” (2010) and “In Time” (2011).

According to the MetroWest Daily News, the 28-year-old actor was killed in a three-car crash in Framingham, Mass.
