Convicted child killer Richard Dobeski arrested at Indianapolis library

INDIANAPOLIS (WLS) -- Convicted child killer Richard Dobeski is back in police custody after he was arrested at an Indianapolis library. The Marion County sheriff's office tweeted out a picture of his arrest Thursday afternoon.

They have not said why he was arrested, but he had until Thursday to register as a sex offender.

Dobeski was released last week after more than seven years in prison on molestation and child porn charges.

He was first released in 2003 after serving nearly half of a 40-year prison sentence for killing two siblings, ages 3 and 6, in LaPorte County.
