How to Become a Crime Scene Investigator Forensic Scientist in Rapid City, South Dakota

Rapid City is home to one of the major Crime Scene Investigation (CSI) units in the state of South Dakota. The primary area served by the Rapid City Police Department Evidence Unit is the city of Rapid City (pop.69,854) and surrounding Pennington County (pop. 104,307), but it also provides services to the rest of the state when needed.

In an average year, Pennington County experiences 3,184 crimes, including a small number of murders and rapes. It is the responsibility of the Rapid City Police Department’s Evidence Unit to collect evidence from violent crimes and thefts.

Despite South Dakota’s reputation as a peaceful, rural area, there have been quite a few notable cases involving forensic laboratory science and crime scene investigations:

  • 1982: A man was found dead outside of the town of Deadwood. The reason for his death was determined to be from repeated blows to the head with a heavy, jagged object. Forensic Scientists identified the weapon as a rock and were able to lift fingerprints from the victim’s car door and a cigarette butt found at the scene of the crime. The crime went unsolved until the fingerprint turned up a hit in 2004.


  • 1997: CSI tracked down a kidnapping suspect by the name of Robert LeVoy Anderson. Multiple evidence types were used to connect him to a missing persons case, including fingerprints, DNA, follicle and fiber identifications and tire tread marks. It was later found that he was responsible for at least two other missing persons cases, which included rape and murder.
