Phoenix Detectives Close Cold Murder Case

October 28, 2013  | 

Fingernail clippings taken from a murder victim in 1982 helped Phoenix police make an arrest in the killing last week, after tests confirmed that DNA found under the victim’s nails matched that of a convicted sex offender, the Arizona Republic reports.

The arrest was the latest in a growing file of Valley murder cases once considered unsolvable. Advances in forensic technology have allowed scientists to test miniscule bits of evidence and match the decades-old material with suspects.

Karen Casanova, 28, was found in a vacant field near 20th Street and University Drive at about 5:45 p.m. on Jan. 31, 1982. The body was partially clothed, and investigators determined she was sexually assaulted and smothered, according to court documents, but there were no witnesses and few clues.

Well I am very happy to hear about this new program to solve old cold cases, however there is one cold case very close to my heart, that I hope will get solved soon. On January 17, 1991, sometime after 1am, my cousin, Nichole Aguilera, mother of 2, just 18 years old, was brutally stabbed all over her body, more than 130 times. She lived alone with her six month old baby in the Marco De Niza Projects in Central Phoenix, just south of downtown. Her baby's father was in prison at the time, but his brother in law, a known mentally unstable gang memer, was a supposedly "innocent bystander right outside her apartment". Well, at least that is the character that my uncle played of him, on the "Silent Witness" video. Till this day, there have been no arrests and we, (her family) still haven't heard any rumors of anyone who could have done this to her. I am just so boggled of how this, the most horrible, gruesome murder in history, has not been solved. yet. Thank You
