Phoenix ? A prosecutor said Friday he will seek the death penalty against a man accused of being the Baseline Killer, a serial predator who terrorized residents here for more than a year.

Mark Goudeau, 42, is charged with 94 crimes in all, including nine counts of first-degree murder, 15 counts of sexual assault and 11 counts of kidnapping. Goudeau has pleaded not guilty.

Maricopa County Attorney Andrew Thomas said he concluded the death penalty was an appropriate sentence and cited aggravating circumstances, including multiple killings and crimes carried out in a cruel manner.

A call to Goudeau’s lawyer was not immediately returned.

Goudeau, a former construction worker, is suspected of starting to prey on people at random after he was released from prison in 2004 on armed robbery, kidnapping and aggravated assault convictions.

Police say the killer usually struck at night and wore disguises, including a wig of dreadlocks. The name Baseline Killer came from the Phoenix street where some of the earliest crimes were committed.
