SOUTH MILWAUKEE (AP) — A Milwaukee man charged with killing and mutilating a woman whose body parts washed up on a beach along Lake Michigan pleaded not guilty during a court appearance Monday.

Maxwell Anderson, 33, of Milwaukee, entered the plea to charges of first-degree intentional homicide, mutilating a corpse and arson in the death of Sade Robinson, 19.

Anderson waived his right to a preliminary hearing. He’s due back in Milwaukee County Circuit Court on May 16, local news outlets reported.

The court appearance was Anderson’s first since his arrest on April 4, two days after a leg believed to belong to Robinson was found by a passerby down a bluff at Warnimont Park along Lake Michigan in Cudahy. The leg had been severed just below the hip.

A torso and an arm believed to belong to Robinson were found Thursday morning along a remote stretch of tree-lined beach in South Milwaukee about a quarter of a mile (400 meters) from an apartment complex, the Milwaukee County Sheriff’s Office said.
