A Long Beach teenager accused of strangling a young woman on a footbridge last week was indicted by a grand jury Friday.

Maxwell T. Sherman, 18, is expected to be arraigned sometime next week on the indictment, which was revealed by Nassau prosecutors during a brief proceeding before District Court Judge Francis Ricigliano in Mineola.

The indictment remains sealed and specific charges aren't known, but police had charged Sherman with second-degree murder in the killing of Lauren Daverin, 18, of Lynbrook.

Her partially clothed and bloodied body was found about 10 p.m. on Aug. 22 on the Mill Pond footbridge spanning eastbound Merrick Road in Rockville Centre, police said. Residents nearby described the area as a popular late-night gathering place for teenagers.

Assistant District Attorney Everett Witherell told the judge Friday that an indictment had been secured, and the judge said that removed it from his jurisdiction. The arraignment will be held in county court, where felonies are tried.

Sherman sat in handcuffs against the courtroom wall during the proceeding. His attorney, William Petrillo of Garden City, said afterward that the indictment was expected.

"A grand jury indictment in a situation like this doesn't come very much as a surprise. There's a very low burden of proof in the grand jury in order to obtain an indictment," he said.

Police haven't revealed what led detectives to Sherman, the extent of his relationship with Daverin, who was married, or a possible motive in the killing. He is being held without bail.
