Alaska failed to obtain DNA samples from 21,000 people accused of crimes, contrary to state law

Alaska Gov. Mike Dunleavy said Tuesday that state law enforcement agencies had failed to collect the DNA of more than 21,000 people arrested for a variety of crimes, contrary to Alaska law.

The Anchorage Daily News and ProPublica reported in December that some law enforcement agencies were not aware of the law or were not following it. As a result, officials neglected to collect DNA swabs that might have solved cold cases and put serial offenders behind bars.

The governor vowed that police, Alaska State Troopers and corrections officials would follow the law going forward and would try and track down the missing DNA.

The Department of Public Safety estimates that Alaska authorities have failed to collect DNA from about 1 in 4 qualifying arrests and convictions since 1995. The lapse violated a state law passed with fanfare in 2007 that was going to put Alaska at the leading edge of solving rape cases.

Since May, the Dunleavy administration rejected a series of Daily News and ProPublica public records requests for information on the backlog, and first made the numbers available in a news conference Tuesday.

Of the 21,577 people whose DNA should have been collected, 1,555 are now dead, according to an accompanying report by the Department of Public Safety. A statement by the governor’s office said Dunleavy has now directed the department to collect DNA from the remaining 20,022 people.


Alaska is now one of at least 31 states that require DNA samples to be collected upon arrest or when criminal charges are filed against a person. The swabs are meant to be sent to the state crime lab, where the DNA would be extracted and could be matched against evidence from cold cases and kept on file to aid in future cases.

The evidence could be used not only to solve sexual assault cases, but also homicides, burglaries and other crimes, and even exonerate the wrongly convicted.

But as recently as December, the Daily News and ProPublica found, some Alaska police departments were unaware of the law or had only recently started collecting the required DNA samples.

The failure was perhaps most striking in the case of accused serial rapist Alphonso Mosley, whose DNA was not submitted to the state crime lab following a qualifying arrest in 2012. In the years that followed, prosecutors say, Mosley committed three more rapes across the city, impregnating one of his victims. Even when he was arrested a second time for domestic violence in 2015, no DNA was collected, contrary to state law.

Until now, it had been unclear just how many people who’d been arrested Alaska police, troopers and corrections officials failed to swab for evidence. The news organizations filed a public records request on May 20 asking for any preliminary estimate on the number of missing or owed DNA samples and for the names of those who “owe” a DNA sample to the state.

The state Department of Public Safety denied that request and a subsequent attempt to appeal, and also denied a request for copies of meeting notes from a state working group that discussed the issue.

On Tuesday, Deputy Attorney General John Skidmore said the state didn’t release the numbers earlier because the data was spread across various law enforcement software systems. ”We had to do searches in each system and try and reconcile the reports that came out of each system to make sure we had a clear understanding of what those numbers were.”

A Dunleavy spokesperson said the effort to determine the number of missing samples began in December 2019 and involved the departments of public safety, law and corrections.

Skidmore said the Department of Law would continue to withhold the identities of people whom law enforcement failed to swab for DNA.

Asked if the state anticipates legal action by victims of offenders who might have been in jail had their DNA been collected as required by state law, Skidmore said “No.”

The problem of states passing DNA collection laws that are ignored or partially implemented is being discovered on a national scale and is sometimes known as “owed DNA.” It involves people arrested, convicted or sentenced for crimes who now “owe” a DNA sample because authorities neglected to collect or process it.

Researchers in Ohio were among the first to quantify the problem, reporting in 2019 that about 15,300 DNA samples had been missed in Cuyahoga County. The Tennessee Bureau of Investigation estimates that there are more than 76,000 missing DNA profiles from felony offenders in that state, based on preliminary research.

The attorney general’s office in Washington state, Alaska’s nearest neighbor, calculates that “tens of thousands” of people legally owe the state DNA samples for entry into the FBI’s Combined DNA Index System (CODIS).

As for collecting the missing Alaska samples, Skidmore said state law allows for someone convicted of certain crimes to be charged with a new felony if they refuse to provide DNA, which may provide a tool for tracking down the “owed” samples. (Under state law, someone who is swabbed for DNA at the time of their arrest but is ultimately not found guilty of the crime can ask to have their sample removed from the system, he said.)

The Department of Corrections will be “the primary point of contact” for DNA collection, Dunleavy spokesman Corey Young wrote in an email Tuesday. In addition to obtaining samples from people who are currently incarcerated, probation and patrol officers will assist in the collection of samples from people who are on supervised release, while booking procedures will ensure a sample is taken whenever someone is taken into custody for a qualifying crime, he wrote. In addition, people who are on the Alaska sex offender registry and still owe a DNA sample will be swabbed when they first register or renew registration.

The thousands of missing DNA samples might help explain why the effort to test a backlog of unexamined rape kits for DNA has yielded only one new prosecution.


Alaska Public Safety Commissioner James Cockrell called the collection effort a top priority for his department. People who owe a DNA swab to the state will be contacted through the Department of Corrections if possible, he said, or local and state law enforcement may work together to locate them and collect a sample.

“Our No. 1 priority will be for violent offenders and sex offenders,” he said.
