Jurors convicted a Long Beach man on Wednesday of raping two teenage girls and a 20-year-old woman all in the span of about a month in South Los Angeles, according to authorities.

In two of the cases, he forced the victims into his car at knifepoint before sexually assaulting them, prosecutors said.

After deliberating for about a day, jurors found 31-year-old Samuel Alexander Vasquez guilty on two counts of kidnapping, three counts of forcible rape, and one count each of forcible oral copulation and assault with a deadly weapon, the Los Angeles County District Attorney’s office announced.

Vasquez’s spree began on Sept. 27, 2016 when he raped a 16-year-old girl in his car after kidnapping her while she walked home near 75th and Figueroa streets, according to authorities.

On Oct. 19, 2016, Vasquez struck again when he picked up a 20-year-old who he then sexually assaulted, prosecutors said.

Then, on Oct. 28, Vasquez again kidnapped another girl at knifepoint and raped her in his car near 70th and Flower streets, prosecutors said. She was 14, according to authorities said.

“He also tried to inject her with a syringe,” prosecutors said.

Police arrested Vasquez as he was leaving work in Long Beach in November 2016.

He could face a maximum sentence of life in prison. His next court date is scheduled for March 20.
