OPINION OF THE COURT

Roberto Gomez appeals his sentence based on a violation of 8 U.S.C. 1326(a) and (b)(2) for illegal reentry into the United States. He was sentenced to 57 months imprisonment and a 36-month term of supervised release. Because the District Court both incorrectly calculated the sentence enhancements under the guidelines and applied the guidelines as mandatory, we remand for resentencing. The Government agrees.

Gomez was arrested in 1997 for possession of heroin with intent to distribute, and *146 in 1998 became a cooperating witness in a drug investigation. In 1999, he pled guilty to possession of heroin with intent to distribute, perjury, and false representation of United States citizenship, but was given a downward departure in sentencing due to his help providing information leading to the arrest of a major drug trafficker and his subsequent grant jury testimony. He received one sentence of 18 months imprisonment for the three charges. After his release from prison, he was deported to the Dominican Republic.

Gomez asserts that once in the Dominican Republic, he and his family received death threats in retaliation for his cooperation with the government. He states that he illegally reentered the United States to escape the threats. He was arrested in March of 2004, and in September of 2004 he was sentenced to 57 months imprisonment and 36 months of supervised release for illegal reentry to the United States after deportation under 8 U.S.C. § 1326(a) and (b)(2).

Gomez asserts, and the Government agrees, that the District Court applied the Sentencing Guidelines as mandatory. Gomez objected to the mandatory application of the Guidelines at sentencing. In view of the Supreme Court’s recent decision in United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), the Sentencing Guidelines should be treated as advisory. Given that the District Court applied the minimum sentence possible under the guidelines and the alleged circumstances of the reentry, Gomez may have received a lighter sentence if the Guidelines were taken as simply advisory. We therefore remand for resentencing under Booker.

In determining the defendant’s criminal history under the Sentencing Guidelines, the District Court added three points for his conviction for possession with intent to distribute and three points for the perjury and false representation of U.S. citizenship conviction. Under the Sentencing Guidelines, however, three points are to be assigned for “each prior sentence of imprisonment exceeding one year and one month” and a “prior sentence” is defined as “any sentence previously imposed upon an adjudication of guilt.” U.S.S.G. § 4Al.l(a) & 4A1.2(a)(l). Because the convictions were consolidated for sentencing, and Gomez received a single 18-month sentence for all three charges, he should have only received three criminal history points for the sentence.

Although Gomez did not object to the District Court’s computation of his criminal history under the Guidelines, we anticipate the District Court will correct this error in determining the advisory Guideline range upon remand.

For the foregoing reasons, the District Court’s sentence will be vacated and the case remanded for resentencing.
