A Detroit-area man has pleaded no contest to first-degree murder, assault with intent to murder and unlawful imprisonment in the killing of a radio news anchor and an attack on his family.

Arthur Williamson's plea was made Thursday in Macomb County Circuit Court in Mount Clemens, the county prosecutor's office said.

A no-contest plea is not an admission of guilt but is used as such at sentencing.
