Local law enforcement agencies saw a disturbing trend in 2011 of out-of-state crews coming into the area to sell illegal drugs, everything from marijuana and methamphetamine to illegal prescriptions, cocaine and heroin.
"This is just following a national trend that has hit here," said Lt. Darin Parke with the Weber-Morgan Narcotics Strike Force.
Those sellers are then transferred by their "employer" to another city, like Denver or Chicago, before police officers can arrest them, Parke said.
"As soon as we can identify the players, the players are changed and we're back to square one," he said.
Parke said that is just one of the crime trends that appears to be increasing this past year. Another trend on the increase is the use of heroin.
The reason: cost. It's cheaper to buy heroin from Mexico than to buy the popular painkiller oxycodone, officials say.
An oxycodone addict would spend $80 to feed their habit, but $20 worth of heroin can deliver the same high, Parke said.
Also, he said, production of the illegal drug has increased by 300 percent in Mexico in the past couple of years.
Davis County Attorney Troy Rawlings said the number of heroin cases in his office has increased the past three years, while oxycodone cases have dropped dramatically.
Box Elder Sheriff Lynn Yeates said his county is also witnessing an increase in the use of heroin "because it is cheaper and easier to get hold of."
Not all areas are seeing an increase in heroin.
In Clearfield, the increase in illegal drug use has been in spice, methamphetamine and prescription drugs, said Assistant Police Chief Mike Stenquist.
And with the increase in the use of illegal drugs, law enforcement also saw an increase this past year in assaults and aggressive behaviors, Stenquist said.
Lt. Mark Chatlin with the Davis Metro Narcotics Strike Force said his agency is still dealing with the same issues it has in the past several years: methamphetamine and marijuana.
The agency has seen an increase in the reports of illegal use of pharmaceutical drugs, but part of that is because his agency hired a full-time pharmaceutical drug crimes detective this year, he said.
That detective investigates all fraud and forgery of prescriptions, plus doctor-shopping cases, Chatlin said.
Bountiful Police Chief Tom Ross said drug cases, including the use of heroin, have significantly increased in his city.
He attributes part of that increase to a more aggressive approach by investigative officers.
Also, more people in his area seem to be addicted to prescription medications and then turn to heroin because it's cheaper, Ross said.
A scary trend he has seen this past year is the increase in identity theft. Some of that is happening because addicts burglarize vehicles and mailboxes and use what they find to fund their habit.
"People need to be more careful about their personal information and not leave them where others can get them," Ross said.
"Identity theft can be so devastating and can take years to resolve."
