HOUSTON, Texas (KTRK) -- The Texas Attorney General's Office says a missing person cold case has been solved after partial human remains were identified as those of 15-year-old Kristen Galvan.

"Yeah, yeah, it's a great feeling," Montgomery County Sheriff cold case detective Fadi Rizk said.

"These things can span months or even years." Rizk said Galvan was first reported missing out of Spring in January 2020 after becoming a victim of sex trafficking.
