The public library, ask the librarian if they know which book would have the information about your cousin's murder, you could tell them the date of the murder and the name of your cousin.

Catch the killer and make him pay, good luck.

Local Newspapers of the time, for which the Library in Albuquerque will probably be your best bet.

And if it is anything like over here in Blighty, you may have to book to get a seat, as there are more and more people checking their family trees and looking at what their relatives got upto in the past.

Ginny Jin beat my to the answer! In google, be specific. Use the exact date (date, day, year and the name of the event)

google, library or police records. if you have the date maybe newspapers of the time.

My cousin was murdered in early 1991 in Albuquerque. I don't have any info on the guy that killed him. I am trying to get some information every option I've tried leads me nowhere fast. My family acts like my cousin never even lived. Any suggestions would be helpful.
