MICHAEL
v.
The STATE.
No. A98A1709.
Court of Appeals of Georgia.
October 28, 1998.
*428 Hector R. Cora, Gainesville, for appellant.
Daniel J. Porter, District Attorney, Donald P. Geary, Assistant District Attorney, for appellee.
*427 HAROLD R. BANKE, Senior Appellate Judge.
Joseph Michael was convicted of possession of marijuana with intent to distribute. He enumerates seven errors on appeal.
This case arose after a Federal Express driver notified police that a damaged package due for delivery appeared to contain marijuana. After verifying its contents, officers left the package outside the residence to which it was addressed and set up video surveillance.
Eventually, Laura Mattox drove up with her young child and picked up the package. When the officers intercepted her, she admitted that two similar boxes were in the back of her truck. She explained that she received $250 for each box she delivered to "Joe," who ran an herbal store in Atlanta.
At the officers' request, Mattox set up a meeting with Joe at a local car dealership by complaining of car trouble and arranging for him to meet her there and retrieve the packages while she left her car for repairs. The officers then videotaped Michael as he arrived, looked around suspiciously, and asked Mattox if she had been followed. After Michael placed the boxes in his car, Mattox mentioned getting paid when she got home, and he nodded his head and later said yes. When Michael was arrested shortly thereafter, officers discovered $870 on his person. Held:
1. The evidence was sufficient to support the verdict. Assuming solely for the sake of argument that Mattox was an accomplice, notwithstanding the arresting officer's opinion that she was a mere pawn, the record provides adequate corroboration of her testimony. Parkerson v. State, 265 Ga. 438(2), 457 S.E.2d 667 (1995) (even slight evidence of corroboration connecting a defendant to a crime satisfies the requisites of OCGA § 24-4-8 and that may be entirely circumstantial).
The videotape showed that Michael was suspicious when he arrived at the dealership and inquired whether Mattox had been followed. Both Mattox and the arresting officer testified that when Mattox mentioned payment upon arrival at her house, Michael *429 agreed. Further, funds sufficient to pay $250 for each of the three packages were seized from Michael's person. This evidence, viewed in the light most favorable to the verdict, was sufficient to corroborate Mattox's testimony. See Sharpe v. State, 213 Ga.App. 280, 282(1), 444 S.E.2d 600 (1994). Combined, they raise a jury question on whether Michael possessed the marijuana with intent to distribute.
2. The trial court did not err in denying Michael's motion for continuance to permit defense counsel to investigate evidence related to the packages sent to Mattox. Michael argues that he needed more time to obtain documentary evidence offered for impeachment subpoenaed from Federal Express showing that Michael had not previously sent Mattox packages. McTaggart v. State, 225 Ga.App. 359, 362(1), 483 S.E.2d 898 (1997) (satisfaction of each statutory ground is necessary to justify continuance).
The record shows that Michael sent previous packages via other delivery services and to Mattox's relatives at other addresses, facts which eliminate any reasonable probability that the admission of the evidence at issue would have affected the verdict. Dowis v. State, 232 Ga.App. 111, 113(2)(a), 501 S.E.2d 275 (1998). We decline to reach the remaining arguments asserted in this enumeration. Guest v. State, 229 Ga.App. 627, 628(1), 494 S.E.2d 523 (1997) (Appellants may not enlarge their enumerations through their briefs).
3. Michael argues that the trial court erred by admitting similar transaction evidence without complying with Uniform Superior Court Rule 31.3. We question whether the evidence at issue, Mattox's comment that she had picked up boxes for Michael four or five times before, could properly be characterized as similar transaction evidence. USCR 31.3, by its nature, applies only to "`other criminal acts by the defendant,' " and no evidence of the other boxes' contents was introduced. King v. State, 230 Ga.App. 301, 302(1), 496 S.E.2d 312 (1998). In any event, because Michael failed to object to the admission of this testimony, the issue was waived. Kim v. State, 230 Ga.App. 342, 343, n. 1, 496 S.E.2d 272 (1998).
4. Michael maintains that the State failed to reveal the deal Mattox received for testifying. The record shows that the arresting officer believed Mattox's claim of ignorance about the package's contents. He did not press charges. He denied threatening to prosecute if she did not cooperate or offering her anything for her assistance. The State also specifically denied the existence of any deal.
Without question, in response to the appropriate defense filings, the State must reveal any agreement, even an informal one, concerning criminal charges against that witness. Owen v. State, 265 Ga. 67, 68(2), 453 S.E.2d 728 (1995). However, because the record reveals no prosecutorial misconduct or any false testimony regarding a deal involving Mattox, Michael's reliance on Giglio v. United States, 405 U.S. 150, 92 S.Ct. 763, 31 L.Ed.2d 104 (1972) is misplaced. Anderson v. State, 193 Ga.App. 540, 541(2), 388 S.E.2d 351 (1989). Moreover, the alleged "deal" developed in this record lacked sufficient specificity to support a finding that it offered even marginal benefit to Mattox. See Patillo v. State, 258 Ga. 255, 260(4)(c), 368 S.E.2d 493 (1988). We also observe that Michael's cross-examination of Mattox did not delve into the question of a deal. Compare Lariscey v. State, 254 Ga. 241, 243(4), 328 S.E.2d 213 (1985).
5. The trial court did not err in denying Michael's motion for new trial based on newly discovered evidence that Federal Express found no record of transporting packages to Mattox or her various aliases at the addresses she specified at trial. The standard for granting a new trial based on newly discovered evidence is the six-criteria test set forth in Timberlake v. State, 246 Ga. 488, 491(1), 271 S.E.2d 792 (1980). Riggins v. State, 230 Ga.App. 757, 758(2), 498 S.E.2d 117 (1998). All six criteria must be met to warrant a new trial. Id. at 758-759(2), 498 S.E.2d 117.
Here, as noted, the record shows that Michael utilized delivery services other than just Federal Express. This fact mandates a finding that the evidence was not so material *430 that it would probably have produced a different result. Young v. State, 269 Ga. 490, 492(2), n. 5, 500 S.E.2d 583 (1998). Further, apparently the evidence was offered solely to impeach Mattox's statement that she picked up several other packages for Michael. Id. Michael's failure to satisfy the Timberlake criteria precludes a finding that the trial court abused its discretion in denying the motion for new trial. Riggins, 230 Ga.App. at 759(2), 498 S.E.2d 117.
6. Michael argues that the admission of a videotape of the transaction between him and Mattox without the proper foundation requires reversal. Michael's failure to timely assert this objection and indicate the missing foundational elements waived the issue. Tolver v. State, 269 Ga. 530, 531-532(2), 500 S.E.2d 563 (1998).
7. Michael maintains his trial counsel was ineffective in seven specific ways. We disagree.
To establish ineffectiveness, a defendant must prove that trial counsel's performance was deficient and but for the deficiency a reasonable probability existed that the result of the trial would have been different. Strickland v. Washington, 466 U.S. 668, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984); Brown v. State, 257 Ga. 277, 278(2), 357 S.E.2d 590 (1987). An error by counsel, even if professionally unreasonable, does not warrant reversal of a criminal conviction if it had no effect on the judgment. Goodwin v. Cruz-Padillo, 265 Ga. 614, 615, 458 S.E.2d 623 (1995). Further, we need not inquire into counsel's alleged deficiency, absent a showing of prejudice. Trammel v. State, 265 Ga. 156(1), 454 S.E.2d 501 (1995). Review of counsel's performance must be highly deferential. Rogers v. State, 195 Ga.App. 446, 448(2), 394 S.E.2d 116 (1990).
(a) Michael asserts that trial counsel's failure to interview Mattox prior to trial was ineffective. However, the record shows that trial counsel questioned Mattox during related forfeiture proceedings. Michael's failure to demonstrate prejudice from the alleged deficiency is fatal to this argument. Goodwin, 265 Ga. at 615, 458 S.E.2d 623.
(b) Michael maintains that trial counsel's failure to assert a lack of foundation objection to the admission of the videotape of the transaction constitutes ineffectiveness. The fact that the State laid an adequate foundation for the videotape's admission undermines this argument. See Wingfield v. State, 226 Ga.App. 448, 449(2), 486 S.E.2d 676 (1997). Because a witness was available to testify about the tape's accuracy, State v. Berky, 214 Ga.App. 174, 176, 447 S.E.2d 147 (1994), vacated, 266 Ga. 28, 463 S.E.2d 891 (1995), is inapplicable.
(c) Michael failed to show a reasonable probability that the result of the trial would have been different had counsel successfully excluded Mattox's statement that she had picked up boxes for Michael four or five times before, particularly in view of the substantial evidence showing guilt and the dearth of evidence showing that the other boxes contained contraband. See Goodwin, 265 Ga. at 615, 458 S.E.2d 623.
(d) This same reasoning applies to Michael's contention that trial counsel was ineffective for failing to object to the arresting officer's perception that Mattox knew nothing about the marijuana. See Yi v. State, 267 Ga. 171, 172-173(2), 475 S.E.2d 623 (1996).
(e) The record refutes Michael's contention that trial counsel's failure to lay a foundation for striking two jurors constituted ineffectiveness. The record shows that trial counsel objected that one juror's ties to law enforcement and the other's to Federal Express rendered them incapable of impartiality.
(f) Michael claims trial counsel was ineffective in failing to properly present character evidence. Because the record shows that she did present favorable evidence of his character and Michael failed to specify how counsel erred or what evidence she failed to elicit, prejudice cannot be established.
(g) Michael maintains that trial counsel's decision not to present rebuttal evidence concerning threats Michael made to Mattox constituted ineffectiveness. However, his failure to specify the nature of the *431 potential rebuttal evidence which could have had a reasonable probability of affecting the outcome of his case precludes a showing of prejudice.
Judgment affirmed.
