Investigators may have made a break in the Golden State Killer case, with sources reporting a possible arrest.

According to Fox40, sources with knowledge of the investigation have confirmed a major break in the cold case, and the Sacramento County Sheriff’s Department may have made an arrest.

The Golden State Killer, also known as the East Area Rapist, is one of the most prolific serial killers in the country’s history and has eluded authorities for decades. The killer is believed to be responsible for 12 homicides, nearly 50 sexual assaults and over 100 burglaries in northern California between the late 1970 and late 1980s.

Michelle McNamara, a crime blogger who died in April 2017, had been closely studying the case at the time of her premature death. Her book,  I’ll Be Gone in the Dark, was published posthumously this year and garnered renewed attention in the case.

California authorities are expected to provide more information on Wednesday.

This is developing story. CrimeOnline will provide further updates when more information is available.
