A Walworth man with an earlier child sex conviction could spend the rest of his life in prison after prosecutors charged him Wednesday with repeatedly sexually assaulting a child.

The charge Lawrence C. Hisel Jr., 30, of N1510 Six Corners Road, now faces includes a persistent repeater enhancer, which stems from a 2008 conviction of second-degree sexual assault of a child.

Hisel, who also uses the name Larry, was sentenced in 2008 to five years of probation and one year in jail with work release. He was also ordered to register as a sex offender.

Walworth County prosecutors Wednesday released new allegations that Hisel had sex with a girl as young as 12 about eight times between October 2015 and May 2017, according to the criminal complaint.

Elkhorn police Aug. 2 spoke with a girl who said Hisel sexually assaulted her at her home, his home, in his car in a fast food restaurant’s parking lot and at Babe Mann Park in Elkhorn, the complaint states.

Hisel, who has previously listed a town of Darien address, also was charged this year in another alleged child sex crime.

In March, police arrested Hisel on suspicion of trying to meet a juvenile. A Walworth County sheriff’s detective posed as a 15-year-old girl on the app Whisper, where Hisel sent sexually explicit messages and pictures, according to that criminal complaint.

In that case, which is ongoing, Hisel was charged with using a computer to facilitate a sex crime, soliciting intimate representations from a minor, child enticement as a persistent repeater and failure to register a username with the sex-offender registry.

The child enticement charge carries the same enhancer as Hisel’s newest charge, requiring a life sentence without the possibility of parole.

Judge Phillip Koss on Aug. 22 ordered Hisel held on a $500,000 cash bond, court records show.

Hisel was scheduled to make his initial appearance in Walworth County Court at 1:15 p.m. Thursday.
