A man convicted of sexually assaulting three Porterville-area girls, one of him his stepdaughter, faces a prison term of up to 229 years when sentenced next month, the Tulare County District Attorney's office announced Friday.
Keven Grisham, 52, of Santa Maria was convicted June 18 by a Tulare County Superior Court jury. He was found guilty on 21 counts of sexual assault, including child molestation, forcible rape and sodomy, and unlawful sexual intercourse with a minor, according to the press release.
Prosecutors said the offenses occurred between 1996 and 2003, when Grisham was living in the Porterville area and when the three victims, now in their early- to mid-20s, were minors.
Grisham's arrest, in Santa Maria in October last year, followed a monthlong investigation that began after a then-23 year-old woman told Tulare County sheriff's deputies that Grisham, her stepfather, had sexually assaulted her between the ages of 11 and 18, according to a sheriff's report.
During the investigation, two other victims approached the sheriff's department and told deputies they had been sexually assaulted by Grisham when they were minors, said Deputy District Attorney Mikki Verissimo, who prosecuted the case.
The assaults occurred in the Porterville area, Verissimo said.
"I'm very happy with the verdict and I'm happy that we got justice for the three victims," she said.
Grisham will be sentenced July 22 in Tulare County Superior Court.
