Table 1: Number leaving ICE detention
from this facility

During the most recent 12 month period for which data are available, a total of 27 detainees housed at the Denver County Jail left that facility because they were deported, were released under supervision while their cases were being decided, or left ICE detention for one of a variety of other reasons. The use of this facility for the temporary housing of federal immigration detainees was arranged through an intergovernmental service agreement (IGSA) under which payments by ICE to another governmental agency are made for housing federal detainees. Additional information about the arrangement, including whether a private company may operate the facility for the government, was not available at the time this report was posted.

Those individuals who departed from this facility because they were leaving ICE detention made up 6 percent of the 469 detainees housed at this facility during the last 12 months. This report focuses on the reasons these individuals left ICE detention. Sometimes this report speaks of these individuals as those "exiting" ICE detention, or simply as "exits." The other 94 percent remained in ICE detention but were transferred from the Denver County Jail to other facilities.

This report covers those who left ICE custody. It excludes individuals transferred to other ICE facilities. For more information on this facility, including individuals that were transferred, see additional TRAC reports in this series.

This report series is based upon analyses conducted by the Transactional Records Access Clearinghouse (TRAC) at Syracuse University of 3.4 million government records tracking each individual who passed through an ICE detention facility during the past decade. The most recent 12 month period for which comprehensive data are available is for April 2007 through March 2008. See About the Data.

How This Facility Ranks Nationally

Rankings on the number leaving ICE detention. The Denver County Jail was one of 1,528 facilities that were used to house immigration detainees during the last decade, and one of 654 facilities nationwide that housed ICE detainees during the most recent 12 month period. Of these 654, there were 324 facilities that had at least 10 individuals who were deported or released. Excluding those facilities with fewer than 10 exits, the Denver County Jail last year ranked in the top 80 percent nationwide in the number of individuals leaving ICE detention. This means that 80 percent of the locations contributed the same or a larger numbers of exits, while 20 percent had a smaller number. See Table 1.

Deportations. Nationally, the most common reason that a detainee left ICE detention was that they were deported from the United States. During the most recent 12 month period for which comprehensive data are available, nationwide 81 percent of those leaving ICE detention were deported or "voluntarily" departed. By way of comparison, a lower percentage of detainees (4 percent) left the country from the Denver County Jail because they were formally deported, or left under the so-called "voluntary departure" procedure.

Exit trends are also summarized by fiscal year in Table 2. Year-by-year figures for the Denver County Jail are given for the total number of detainees as compared with those leaving ICE detention from the facility. The percent of detainees that left ICE detention is also given. (As mentioned above, the remaining detainees were transferred to another ICE detention facility.) Because data for all twelve months of the most recent fiscal year are not yet available, the FY 2008 numbers (October 2007 through September 2008) are estimated based upon reporting for the first six months.

Were Detained Individuals from the Local Area?

Information on the place of arrest was not included in the available data ICE released. However, we can examine whether the Denver County Jail was the first ICE facility in which these detainees were held. According to ICE records, for all these detainees, the Denver County Jail was the first place they were sent when they were detained by ICE.

For the United States as a whole, last year the typical detainee stayed in two different ICE detention facilities before being deported or released - half stayed in 2 or fewer facilities, and half stayed in 2 or more. The average number of ICE facilities detainees moved through was 1.9. Detainees at the Denver County Jail on average had stayed at somewhat fewer (1.0) ICE facilities.

Why Did Detainees Leave ICE Detention?

ICE records one of twenty-three reasons a detainee left ICE detention. As shown in Table 3, these reasons fall into ten general categories -- from leaving because one is deported or removed, to leaving because one escaped or the individual died while in custody.

Deportation. As mentioned earlier, while nationally the most common reason that a detainee left ICE detention was that they were deported from this country, this was not the top reason at this facility. At the Denver County Jail only one individual was deported or removed during the most recent 12 month period for which data are available. (ICE data did not distinguish between deportations and removals, and the terms are used interchangeably in this report.)

Transferred to criminal custody. The most common reason a person left ICE detention from this facility was that they were transferred to criminal custody. A total of 17 individuals (63 percent) left this facility last year because they were turned over to U.S. Marshals or to some other government agency. This typically occurs because there is an outstanding criminal case against the individual, or the individual is needed as a material witness in a criminal case.

No legitimate grounds to deport. Sometimes individuals left ICE detention because they "won" their case. Typically this occurs when an Immigration Judge orders the deportation proceedings ICE has filed against them "terminated" (dismissed) and the judge's order after any appeals becomes final. Analysis of the latest 12 months of data show that a total of 6 individuals, or 22 percent were released from detention by the Denver County Jail because a determination was made that there were no grounds to deport the individuals and thus ICE had to release them from custody.

Orders. Orders are additional mechanisms that are sometimes used to release a person while their case is pending, or awaiting removal. Under an "order of recognizance" an individual is released with reporting conditions while in deportation proceedings and awaiting a final decision. A second type of order ("order of supervision") releases an individual after a final order of removal. Here an individual is released because ICE has not met the time limits the law imposes for deporting the individual. There were 2 (7 percent) who left the Denver County Jail detention for these reasons: 2 with orders of recognizance, and none with an order of supervision.

Withdraw entry request. Individuals also leave ICE detention for a variety of additional reasons. One of these is that individuals who have been detained may be allowed to "withdraw" their request to enter the country. If a person withdraws their request, this effectively means they must leave the country. A total of 1 individuals (4 percent) fell into this category. Unlike deportation where the person is legally barred for a period of years and sometimes permanently from coming back to the United States, a person who withdraws their request is not for that reason barred from re-entry into this country.

Escape and death. Nationally, there were 92 individuals who escaped ICE detention during the latest 12 month period for which data are available, and 8 individuals were recorded as having died in detention. No one was recorded by the Denver County Jail as either escaping or dying last year. Over the past decade, there was also no record of anyone who died or escaped from this facility.

As shown in Table 3, no one was recorded as leaving the Denver County Jail during the past 12 months for the following reasons: Bonded out, Paroled and Voluntary departure. See "Reasons for Leaving ICE Detention" for a description of these categories.

Comparing Release Reasons Against The National Picture

In many respects release reasons for the Denver County Jail departed from the national picture. It was the case that a lower proportion left because they were deported from this facility (4 percent) than was true for the U.S. as a whole (72 percent). No one left as a voluntary departure from this facility, while this was true for 10 percent of all individuals nationally.

In addition, differences were seen for those released to the U.S. Marshal or other agency (63 versus 3 percent), persons whose proceedings were terminated (22 versus 2 percent), and individuals released on bond (none versus 8 percent).

The facility's percentages fell within 3 percentage points of the national figures for all other categories.


Which nationalities predominate? Last year in the United States, individuals from Mexico comprised the largest number of those leaving ICE detention. Some 53.6 percent of all detainees recorded Mexico as their country of origin. The Denver County Jail had a much larger proportion of detainees from Mexico - 89 percent among their exits. Detainees from Mexico were also the largest single nationality group among those leaving detention from the facility.
