How Forensics Solved the Case - The Night Stalker.
Transcript of How Forensics Solved the Case - The Night Stalker.
Richard Ramirez was an American serial killer, convicted of 13 murders in California from 1984 and 1985. He was also charged with rape,sodomy,oral copulation, burglary as well as attempted murder. (Deutsch, Thompson)
At the age of eighteen Richard bought a master set of keys to Toyota and Honda cars. With these keys he stole a car nightly. Once he was proficient at this he began to rob houses and eventually assault women. (Grise)
Once Ramirez found the perfect house to break into, darkened with no streetlights, he would park his stolen car and proceed into the house. While the occupants slept during the night, Ramirez would unlock a door or go through a window. If there were any men in the house he would shoot them directly in the temple. The loud gun shot of course woke up the women which he would proceed to tie up. If there were any children in the house they would be forced to watch. If the women were not to much to handle Ramirez would rob them and leave but if they were to much he would escalate. (Grise)

How Forensics Solved the Case
Richard Ramirez was caught by a group of civilians who figured out who he was while he was attempting to steal a car. To accomplish this Ramirez tried to pull a women out of the vehicle. This case was one of the first ones that used automated fingerprinting technology. Today this database gives "likely" matches and a trained fingerprint examiner must compare them to find an actual match. (Crime and Investigation)
The Development of Ramirez
* Born February 28,1960
* Older cousin, Mike, returned from the Vietnam war bringing back with him stories as well as photography depicting how he tortured and mutilated Vietnamese women.
*The teenage years of Ramirez came with many petty crimes in order to fuel his drug addiction.
*Cousin Mike murders his wife in front of Ramirez.
*Car theft in 1983 resulted in jail time.
*Killing spree from June 28,1984 - August 17, 1985.
*Final murder on August 24, 1985.
*August 28, 1985 identification of stolen car complete with his fingerprints inside.
* Media & witnesses & survivors led to his capture the next day.
Audio from Ramirez Trial
- Ramirez left finger prints in the car that he stole. We know that they more than likely used one of the methods such as: Cyanoacrylate or Ninhydrin to lift the prints. From here, they were able to run through the system (IAFIS) to find a likely match. From there a specialist in the lab looked at the finger prints for confirmation.
- Another thing they could have done forensically was test the ropes and things that Ramirez used to tie up the various women. From this they might be able to find DNA, blood or hairs.
