SOUTH MILWAUKEE (AP) — More human remains, including a torso, that are believed to belong to a missing woman have washed up on a beach along Lake Michigan, authorities said Thursday.

The torso and an arm believed to belong to 19-year-old Sade Robinson were found Thursday morning along a remote stretch of tree-lined beach in South Milwaukee about a quarter of a mile (402 meters) from an apartment complex, the Milwaukee County Sheriff’s Office said.

The remains were found by someone walking on the beach, the office said in a news release.

Maxwell Anderson, 33, of Milwaukee has been charged with first-degree intentional homicide, mutilating a corpse and arson in the case. A phone message seeking comment was left Thursday afternoon for one of his attorneys, Anthony Cotton.

Anderson, of Milwaukee, was arrested April 4, two days after a leg believed to belong to Robinson was found by a passer-by down a bluff at Warnimont Park along Lake Michigan in Cudahy. The leg had been severed just below the hip.
