Police: Man raped girlfriend's sisters

South San Francisco police are alleging a man arrested for molestation last week raped at least three of his girlfriend’s sisters, one who was only 5 years old, Detective Ken Chetcuti told the Daily Journal yesterday.

Kyle Clifton Vogt, 36, was arrested Thursday after a two-week investigation by police that revealed he allegedly had carried on a sexual relationship with his girlfriend’s half-sister for at least eight years starting when the victim was just 5.

If convicted, Vogt could face 15 years to life in prison, according to the San Mateo County District Attorney’s Office.

Yesterday, Chetcuti said Vogt will also be charged with molesting two of the girlfriend’s other sisters between 2000 and 2012. Vogt also allegedly molested a fourth girl whose parents he knew, Chetcuti said.

The investigation is ongoing, he said, and other victims may emerge.

Vogt singled out one of the victims, his girlfriend’s younger half-sister, and sexually assaulted her for eight years, police said.

His 30-year-old girlfriend is the oldest of six sisters, police said.

Vogt, a mechanic by trade, was arrested at his home at 1145 Hillside Blvd. in South San Francisco Thursday on suspicion of having sex with a juvenile girl.

Vogt also lived in Davis with his girlfriend and her younger sisters often visited the couple and periodically lived with them in both cities, Chetcuti said.

Vogt threatened some of girls with bodily harm to keep them from talking, police said.

He is being charged with 11 felony counts including one count of aggravated sexual assault with a child, one count of continuous sexual abuse with a child and six counts of lewd acts with a child. Vogt also faces two counts of lewd acts with a minor ages 14 or 15 and one count of showing harmful matter of sexual content to a minor, according to the district attorney’s office.

He is known to have driven a 1980s blue Toyota pickup truck and a burgundy 1970s Chevrolet Monte Carlo, according to police.

He is being held without bail and is due in court this Friday to enter a plea.

Police are seeking the public’s help in finding any additional potential victims. Anyone with information regarding the case is asked to call (650) 877-8910.
