(1) The trial court erred by revoking the defendant’s probation where the State failed to prove violations of the absconding provision in G.S. 15A-1343(b)(3a). The trial court found that the defendant “absconded” when he told the probation officer he would not report to the probation office and then failed to report as scheduled on the following day. This conduct does not rise to the level of absconding supervision; the defendant’s whereabouts were never unknown to the probation officer. (2) The other alleged violations could not support a probation revocation, where those violations were “unapproved leaves” from the defendant’s house arrest and “are all violations of electronic house arrest.” This conduct was neither a new crime nor absconding. The court noted that the defendant did not make his whereabouts unknown to the probation officer, who was able to monitor the defendant’s whereabouts via the defendant’s electronic monitoring device.
