Here is a summary of Katie’s Law:
Katie’s attacker’s skin and blood were found under her fingernails. This DNA profile was sent to the Combined DNA Index System (CODIS) where officials hoped a match would be made. A DNA match identified Gabriel Adrian Avila, who had been arrested in November 2003 for aggravated burglary and was serving time in the New Mexico Corrections System since November 2004. After being confronted with his DNA evidence, Avila subsequently confessed to the murder of Sepich.
The experience of Katie’s parents, Jayann and Dave Sepich, in bringing Katie’s killer to justice motivated them to advocate for legislation that would expand the use of DNA to arrest and convict criminals:
Jayann and Dave Sepich, Katie’s parents, began researching the role of DNA in solving crimes. At first, they just wanted to find and punish the person who had murdered their daughter; but as they learned more about how DNA can solve crimes, they also learned it could do so much more–it can prevent crimes and save lives.
The proposed legislation encourages states to collect a sample through DNA profiling from individuals who are: arrested for, charged with or indicted for crimes involving murder, manslaughter, sexual assaults, and kidnapping or abduction. The collected samples are included in CODIS  which contains more than 5 million records and used by law enforcement agencies. DNA profiling is not the same as full genome sequencing and contains no genetic information. There are over 3 billion markers in the DNA molecule and only 13 of these markers go into CODIS.
