Friends and family came together in Hicksville to remember 18-year-old Lauren Daverin.
The girl's partially nude body was discovered late Thursday night on the Mill Pond footbridge between Sunrise Highway and Merrick Road in Rockville Centre.
Another 18-year-old, Maxwell Sherman, is accused of strangling Daverin.
Sherman, of Long Beach, is charged with second-degree murder and is being held without bail.
On Sunday, friends left candles, flowers and notes on the footbridge where Daverin's body was found.
"She was a really fun person and everyone loved to be around her," friend Samantha Maselli said. "She always had fun. There was a never a boring time when you were around her."
Her older sister posted a note to Daverin on a Facebook page set up to honor the teen.
"To my beautiful baby sister," she wrote. "I love you so much. Every part of my heart is broken and I cannot wait to meet you again in another life."
