We offer an approved 40-hour bloodstain pattern analysis training in Houston. Our company is based in New Braunfels, Texas. The lead instructor, John Calvin Gaziano, is a retired sergeant of the Fremont Police Department with over 27 years of service. He supervised and taught members of the crime scene unit, in addition to being a certified bloodstain pattern analyst (CBPA) with the International Association for Identification (IAI).

This entry-level course is for those investigating violent and bloody crime scenes. The training covers all aspects of bloodstain pattern analysis, from basic to advanced topics. Current techniques and technologies will be introduced. The class includes lectures on various aspects of bloodstain pattern analysis and hands-on practical exercises with animal blood. Attendees will learn to identify bloodstain patterns and understand the mechanisms and events that created them. We teach participants to reconstruct and sequence events while remaining objective and using the scientific method. During the week-long course, 15 practical exercises and related subsets will be introduced. For example, some activities include beating blood with baseball bats, flinging blood onto walls, and shooting blood with a mounted pistol. A 233-page manual written by the instructor will be provided to each student. 

The International Association of Bloodstain Pattern Analysts (IABPA) Education Committee and the International Association for Identification (IAI) Bloodstain Pattern Examiner Certification Board approved the training curriculum. We offer the course throughout Texas, focusing on the AustinSan AntonioDallas, and Houston areas. Please contact us if you are interested in bloodstain pattern analysis training in Dallas and want to host the course.

We look forward to working with you and your organization.

The shape of individual bloodstains found at crime scenes can range from entirely circular to very elliptical. The different shapes correspond to the angle of impact with a target surface. Being able to interpret a stain’s impact angle allows the analyst to correlate multiple stains in an associated impact pattern and determine their area of origin.

What are the benefits and requirements of hosting the Bloodstain Pattern Analysis training course in Houston?

Hosting the bloodstain pattern analysis course has several benefits for the agency. One advantage is eliminating costs associated with travel and lodging for employees. Another benefit is that the hosting agency or organization receives free tuitions based on the number of paying students as follows:

  • One free tuition if the course has 14 paying students.
  • Two free tuitions if the course has 18 paying students.
  • Three free tuitions if the course has 22 paying students.

The course requires a minimum of 10 paying students. If the minimum number of paying students is not met, the class will be canceled, and all tuitions paid will be promptly refunded.

We require the agency or organization to provide a lecture room for digital media presentations to host the bloodstain pattern analysis course. A large and clear area will also be needed for the practical exercises, and a warehouse-type room usually works well. One of the practical exercises requires a location where a pistol can be fired safely for a few hours during one of the training days.

The responsibility of the hosting agency or organization is to aid in recruiting students for the course. We will supply a course flyer to be distributed to nearby agencies, and we will post the course on various websites. All travel and associated costs are the responsibility of Gaziano Forensic Consulting and not the hosting agency.
