LOCKPORT – Kelly P. Chellino, a Level 2 sex offender, pleaded guilty Thursday in Niagara County Court to a felony count of driving while intoxicated.

Chellino, 44, of Park Avenue, Waterport, was arrested Nov. 30 in the City of Lockport.

Chellino was promised a sentence of no more than a year in jail when he returns before County Judge Sara Sheldon Farkas on Sept. 19.

Chellino has been on the sex offender registry since his 1997 conviction for having sex with a 14-year-old girl.

He was convicted of drunken driving in the wake of a 2004 head-on crash in Lewiston that resulted in the death of one of his passengers, Christina M. Jones, 18, of Lockport.

The other driver, Jason D. Jakubec of Wilson, who also was drunk and crossed the center line to cause the wreck, pleaded guilty to criminally negligent homicide and served 2½ years in state prison.
