Tim Lambesis, lead singer for the heavy metal band As I Lay Dying, was arrested in California on Tuesday on charges that he sought the help of an undercover detective to have his estranged wife killed.

Lambesis was taken into custody in Oceanside, near San Diego.

Police had previously learned Lambesis was looking for someone to carry out the killing, but would not give any details as to his motive. His wife, Meggan, filed papers in San Diego Superior Court in September 2012 seeking dissolution of marriage.

Lambesis is a founding member of As I Lay Dying. He will appear in court for an arraignment on Thursday, May 9th.
