Mitotyping Technologies - The clear choice for forensic mitochondrial DNA and STR analysis featuring 72-hour turnaround time for DNA identification of human remains.

Mitochondrial DNA testing from a Mitotyping case, U.S. v. Beverly, was reviewed by the Sixth Circuit Court of Appeals. The science of mitochondrial DNA testing was upheld. This is the only federal appellate decision concerning mitochondrial DNA published to date.

Outlaw Wild Bill Longley twice cheated the noose, but popular Texas folklore that he got away a third time is proved wrong with help from Mitotyping Technologies.

Legal Resources
Critical Reading
To prepare our clients for courtroom testimony, we recommend that all attorneys read the articles. We will then discuss the articles with you in depth to prepare for trial. There is no charge for any phone consultation of this type.
We also recommend an online mtDNA tutorial, which can be found as a separate module within an interactive tutorial titled "Principles of Forensic DNA of Officers of the Court" at
Mitochondrial DNA Databases
A mitochondrial DNA database for North America is found at  This excellent database is maintained by The Institute for Legal Medicine, Innsbruck Medical University.
Statistical Calculations
Mitochondrial DNA statistical calculations are based on simple sampling equations. For an introduction to the calculations and their interpretation.

Testimony Foundation Questions
We have provided a basic set of foundation questions for mitochondrial DNA testimony. Cases will have different requirements, so we encourage website viewers to adapt these questions to their needs.
Jury Education
Jury education is critical when this technology is presented in court. Mitotyping uses five basic overhead transparencies during testimony for jury education (transparencies courtesy of the FBI's DNA Unit II). A basic tutorial takes about 10 minutes and emphasizes the differences between mitochondrial and nuclear DNA typing.
