Rapid City man charged with sexually assaulting 4th girl

Prosecutors have added more charges against a Rapid City man accused of sexually assaulting multiple girls.

A Pennington County jury convicted 38-year-old Teddy Guzman on Thursday of three counts of first-degree rape for sexually assaulting three girls under age 13.

Prosecutors charged him on Wednesday with sexually assaulting a fourth girl in 2015 and 2016 when she was 13- and 14-years-old. Investigators learned about her after police started investigating Guzman in 2017 but she wasn’t ready to testify when the other three girls’ cases went to trial last year.
