Appeal From Lexington County
G. Thomas Cooper, Jr., Circuit Court Judge
Unpublished Opinion No. 2010-UP-301
Submitted May 3, 2010 – Filed June 8, 2010
Appellate Defender M. Celia Robinson, of Columbia, for Appellant.
Attorney General Henry Dargan McMaster, Chief Deputy Attorney General John W. McIntosh, Assistant Deputy Attorney General Salley W. Elliott, and Assistant Attorney General Christina J. Catoe, all of Columbia; and Solicitor Donald V. Myers, of Lexington, for Respondent.
PER CURIAM: Alan Bruce Carruthers pled guilty to one count of criminal sexual conduct with a minor in the first degree and was sentenced to thirty years' imprisonment. He appeals, arguing his guilty plea failed to comply with the mandates set forth in Boykin v. Alabama, 395 U.S. 238 (1969). Specifically, Carruthers contends the plea court erred in accepting his plea without first ordering an evaluation to determine his mental competency. We affirm pursuant to Rule 220(b)(1), SCACR, and the following authorities: In re Antonio H., 324 S.C. 120, 122, 477 S.E.2d 713, 714 (1996) (explaining that when the determination of competency is not raised at the time of the guilty plea, it is procedurally barred on appeal); State v. McKinney, 278 S.C. 107, 108, 292 S.E.2d 598, 599 (1982) ("Absent timely objection at a plea proceeding, the unknowing and involuntary nature of a guilty plea can only be attacked through the more appropriate channel of [p]ost-[c]onviction [r]elief.").
FEW, C.J., THOMAS and PIEPER, JJ., concur.
 We decide this case without oral argument pursuant to Rule 215, SCACR.
