The mission of AZ Forensic Associates is to responsibly handle and provide an objective and accurate evaluation of each case in our custody.

The vision of AZ Forensic Associates is to assist with the standardization of bloodstain pattern analysis, its acceptance and appropriate usage in conjunction with other forensic tools.

What is bloodstain pattern interpretation/analysis?

Analysis/interpretation of the size, shape and distribution of bloodstains where there has been a blood shedding event.

"...When a man who is honestly mistaken hears the truth, he will either cease being mistaken, or cease being honest."
Thomas Paine (1737-1809)
