U.S. Immigration and Customs Enforcement has revealed that 124 illegal immigrant criminals released from jail by the Obama administration since 2010 have been subsequently charged with murder.

A Center for Immigration Studies report on the data from ICE to the Senate Judiciary Committee added that the committee is not releasing the names of the murder suspects.

"The criminal aliens released by ICE in these years — who had already been convicted of thousands of crimes — are responsible for a significant crime spree in American communities, including 124 new homicides. Inexplicably, ICE is choosing to release some criminal aliens multiple times," said the report written by CIS's respected director of policy studies, Jessica M. Vaughan.

She added that 75 percent were released due to court orders or because their countries wouldn't take them back.

What's more, her report said that in 2014, ICE released 30,558 criminal aliens who had been convicted of 92,347 crimes. Only 3 percent have been deported.

Her analysis is the latest shocking review of Obama's open-border immigration policy. And despite the high number of illegal immigrants charged with murder, the list doesn't include those released by over 300 so-called "sanctuary cities" and those ICE declined to take into custody.

She said that 124 criminal aliens released by ICE between 2010 and 2015 were charged with murder during that period and "associated with 250 different communities in the United States, with the most clustered in California, New York and Texas."

In a memo about the subsequent crimes of released illegals to Judiciary Committee Chairman Sen. Chuck Grassley, ICE said, "The aliens were charged with a total of 135 homicide-related crimes subsequent to release from ICE custody. As of July 25, 2015, a total of 39 convictions have resulted from these homicide-related charges. Of the 121 total aliens, 2 had homicide-related convictions prior to release from ICE custody."

Vaughan added that "ICE reported that there are 156 criminal aliens who were released at least twice by ICE since 2013. Between them, these criminals had 1,776 convictions before their first release in 2013, with burglary, larceny, and drug possession listed most frequently."
