In June, Victor Martinez-Hernandez was charged with the murder of Rachel Morin, a mother of five in Maryland. Police in Oklahoma tracked the accused repeat offender down with a sample of his DNA recovered from a Los Angeles home invasion in which a nine-year-old girl and her mother were assaulted. Police say he came to the U.S. illegally to escape prosecution for at least one other murder in his native El Salvador in December 2022.
These gaps have led to broad claims that illegal immigrants have less involvement with the criminal justice system than native-born Americans. A review of the available data, however, shows that the criminal records of millions of migrants—the ones President-elect Trump vows to prioritize for deportation—remain unknown due to illegal crossings, lax enforcement, and lax data collection by federal and “sanctuary” jurisdictions.
In addition, an analysis of the available statistics by RealClearInvestigations suggests that the crime rate of noncitizens is vastly understated. A separate RCI analysis based on estimates developed by the U.S. Department of Justice’s National Institute of Justice (NIJ) suggests that crime by illegal aliens who entered the U.S. by July 21, 2024 cost the country some $166.5 billion. These criminals disproportionately entered the U.S. during the Biden administration.
The problem begins with incomplete initial vetting by the U.S. Immigration and Customs Enforcement (ICE). The criminal histories of migrants from far-flung countries with often shoddy record-keeping are somewhat hard to determine. It is also impractical to hold each person until they have passed a rigorous background check. As a result, ICE routinely releases many illegals into the country on their own recognizance and then discovers afterward that many had criminal records in their home countries.
In the July 21 letter to Rep. Gonzales, ICE reported that 13,099 of these non-detained individuals have convictions for homicide, with 1,845 facing criminal homicide charges. Another 9,461 have convictions for sex offenses (not including assault or commercialized sex), and 2,659 face pending charges. The convictions include other crimes such as assault (62,231), robbery (10,031), sexual assault (15,811), weapons offenses (13,423), and dangerous drugs (56,533).
These figures are only suggestive of the extent of crime because they only list the most serious crime committed by each individual. A murderer, for example, who also committed a sex offense, is only counted as a murderer. It does not include the fact that millions of migrants are violating the law because of their presence in the U.S. It also does not account for the lawbreaking involved in working without proper authorization or the widespread use of stolen Social Security numbers to secure employment.
The 662,566 convicted and likely criminals make up 9 percent of the 7.4 million released noncitizens.
As the Laken Riley and Rachel Morin murder cases make clear, it is difficult to calculate all the victimization costs of crime to families and society.
Half of the crimes these non-detained individuals commit don’t have cost estimates. These crimes include kidnapping, embezzlement, extortion, smuggling, traffic offenses, and weapon offenses.
These criminal illegal aliens entered the U.S. under multiple administrations, but the size of the problem was likely larger under the Biden administration. That isn’t just because so many more illegal aliens were entering the country. Under the Trump administration’s remain-in-Mexico policy, the U.S. Citizenship and Immigration Services (USCIS) performed background checks on immigrants. That included contacting immigrants’ countries of origin.
ICE has been processing criminals as they enter the country, but without identifying them as criminals. So, under the Biden administration, they have simply been released into the country. Now, they are walking freely in the United States, and no one knows where they are.
The estimate of over $160 billion in costs from criminal illegal aliens is very likely an underestimate of the true costs. It assumes the average criminal coming into the country commits only one offense similar to what he committed in his home country. We are also not counting the costs of half of criminal illegal aliens.
