UNPUBLISHED UNITED STATES COURT OF APPEALS FOR THE FOURTH CIRCUIT UNITED STATES OF AMERICA, Plaintiff-Appellee, v. No. 98-7757 SERGIO GONZALEZ, Defendant-Appellant.

Appeal from the United States District Court for the Eastern District of Virginia, at Alexandria.

Albert V. Bryan, Jr., Senior District Judge. (CR-97-264-A, CA-98-1586-AM) Submitted: March 9, 1999 Decided: March 25, 1999 Before MICHAEL and MOTZ, Circuit Judges, and BUTZNER, Senior Circuit Judge. _________________________________________________________________ Vacated and remanded by unpublished per curiam opinion. _________________________________________________________________ COUNSEL Sergio Gonzalez, Appellant Pro Se. Robert Andrew Spencer, OFFICE OF THE UNITED STATES ATTORNEY, Alexandria, Virginia, for Appellee. _________________________________________________________________ Unpublished opinions are not binding precedent in this circuit. See Local Rule 36(c).

OPINION PER CURIAM: Appellant Sergio Gonzalez seeks to appeal the district court's order summarily denying his motion filed under 28 U.S.C.A.§ 2255 (West 1994 & Supp. 1998) without ordering a response from the Govern- ment. See Rule 4(b) of the Rules Governing§ 2255 Proceedings.

Gonzalez and his co-defendant, his wife, were represented by mem- bers of the same law firm. Gonzalez contends that such joint represen- tation created a conflict of interest because it inhibited cross- examination of his co-defendant-wife, prevented Gonzalez from pur- suing an effective defense, and deprived Gonzalez of independent advice as to whether he should testify.

We agree with the district court that the record does not conclu- sively support Gonzalez's claim. However, ineffective assistance of counsel claims generally rely on evidence outside the record. See, e.g., United States v. Tatum, 943 F.2d 370, 376 (4th Cir. 1991) (a fail- ure to act before trial may show a conflict of interest). Furthermore, a § 2255 proceeding is the proper proceeding in which to expand the record to include additional evidence. See United States v. Stockstill, 26 F.3d 492, 498 (4th Cir. 1994); Raines v. United States, 423 F.2d 526, 529-30 (4th Cir. 1970) (before ordering a hearing, the court may wish to dispose of the § 2255 motion on an expanded record).

We also agree with the district court that Gonzalez did not supple- ment his claim with sufficient factual support. We are mindful, how- ever, that pro se filings should be construed liberally. See Haines v. Kerner, 404 U.S. 519, 520 (1972). Rather than a summary dismissal, we find that the better practice is to return the motion to Gonzales with an instruction that he particularize his claims by including addi- tional factual support. See Rule 2(d) of the Rules Governing § 2255 Proceedings.

Accordingly, we grant a certificate of appealability on the claim that Gonzalez's counsel was ineffective because of an actual conflict of interest, vacate the district court's order, and remand for further proceedings consistent with this opinion.* We dispense with oral _________________________________________________________________ *We express no view as to the merits of Gonzalez's claims. argument because the facts and legal contentions are adequately pre- sented in the materials before the court and argument would not aid the decisional process.
