Rostraver police say they have a person of interest who is already in custody in connection with the killing last month of Jennah Siebert.
The 24-year-old was found dead inside her home on Lenity School Road last month.
Police have not released the name of the individual who is in custody or the charges the individual is being held on.
Siebert's Lexus was seen on surveillance video in Monongahela after the killing, and police had earlier released video of a man whom they say had been driving it and stopped at a convenience store.
An investigation is still underway.
