OPINION
In 1996, Kenneth Spiller, Jr. pleaded guilty to aggravated battery, conspiracy to commit murder, and three counts of murder. In exchange for these pleas, the State dismissed two counts of attempted murder and its request for the death penalty or life imprisonment without parole. Spiller was sentenced to concurrent sixty-year terms for each murder conviction, to be served consecutive to twenty years for aggravated battery and thirty-five years for conspiracy to commit murder, for a total sentence of 115 years. In 1998, he filed a petition for post-conviction relief, which was denied after a hearing. In this appeal, he raises two issues:
I. Whether the trial court abused its discretion by finding improper aggravating circumstances to enhance his sentences and to order them served consecutively; and
II. Whether his 115-year sentence is manifestly unreasonable. 1
We affirm the denial of post-conviction relief.
Facts and Procedural History
On January 20, 1995, Spiller and Roman Jones drove to Levester Snelling's house to confront him about a debt. Spiller and Jones had agreed that Spiller would shoot and kill Snelling unless Snelling paid the debt.
Upon their arrival at Snelling's residence, Spiller and Jones confronted Snelling about the debt. After a brief discussion in the hallway, Spiller and Jones decided that Spiller would have to shoot Snelling. The two reentered the room, and Spiller fired a shot at Snelling, who fell to the ground and then fled through a window. Jones entered another room and began shooting its occupants while Spiller blocked the doorway to prevent any avenue of escape. Jones' shooting resulted in the death of three women, and Spiller shot a fourth woman who survived.
Spiller and Jones were initially charged with three counts of murder and two counts of attempted murder. The State later filed a request for the death sentence or life imprisonment without parole.
Over a year later, Spiller entered into a plea agreement with the State. He agreed to plead guilty to the three murder counts as well as amended counts of conspiracy to commit murder and aggravated battery. *1273 In exchange for the pleas, the State agreed to dismiss the two attempted murder counts and withdraw its request for the 'death sentence or life imprisonment without parole. The plea agreement provided that the three murder sentences would be served concurrently but that the parties would otherwise be able to argue as to the appropriate sentence. Thus, the sentence could range from a minimum sentence of thirty years (the minimum for murder and imposition of concurrent sentences on all counts) to a maximum of 125 years (the maximum sentence of sixty years for murder consecutive to maximum sentences of forty-five years for conspiracy to commit murder and twenty years for aggravated battery). The trial court imposed consecutive sentences totaling 115 years (sixty years for murder, thirty-five years for conspiracy to commit murder, and twenty years for aggravated battery).
On June 22, 1998, Spiller filed a pro se petition for post-conviction relief. The State Public Defender entered her appearance a month later, and an amended petition was filed on January 7, 2000. A hearing was held on February 15, 2000, after which relief was denied. Spiller appeals that denial.
Standard of Review
Spiller bore the burden in the post-conviction court of establishing his grounds for relief by a preponderance of the evidence. Ind. Post-Conviction Rule 1(5). Because he is now appealing from a negative judgment, to the extent his appeal turns on factual issues Spiller must show that the evidence as a whole leads unerringly and unmistakably to a decision opposite that reached by the post-conviction court. Harrison v. State,
I. Propriety of the Aggravating Circumstances
Spiller first challenges the trial court's articulation of aggravating cireum-stances in its sentencing statement and sentencing order. When a trial court relies on aggravating or mitigating cireum-stances to deviate from the presumptive sentence, it is required to (1) identify all of the significant mitigating and aggravating circumstances, (2) state the specific reason why each cireumstance is considered to be mitigating or aggravating, and (8) articulate the court's evaluation and balancing of the cireumstances to determine if the mitigating circumstances offset the aggravating ones. Carter v. State,
The trial court articulated the following aggravating cireumstances at sentencing: (1) a prior history of eriminal conduct that included a conviction for operating a vehicle while intoxicated in 1992 and disorderly conduct in 1994; (2) "the imposition of a reduced or the imposition of concurrent sentences would depreciate the seriousness of the crimes committed"; (3) the nature and cireumstances of the crime, including (a) that the crimes were particularly heinous, (b) that five people were shot and three were killed, (c) that the offenses represent "senseless violence," and (d) Spiller's active participation in the crimes; 2 and (4) the "great risk" *1274 that Spiller would commit another crime as reflected by the cold-bloodedness of the killings and the "total lack of respect for human life" that the killings represent. R. at 546-47. It found as mitigating cireum-stances that Spiller "plead[ed] guilty and admitted his guilt, that he has no prior felony convictions [and] that he has cooperated with the State of Indiana." R. at 547. The trial court observed that Spiller had "already received leniency from the State of Indiana for his cooperation in view of the plea agreement...." R. at 547. The trial court found that the aggravating cireumstances, especially the "nature of the crimes, far outweigh the mitigating cireumstances." R. at 548. Spiller contends that some of the aggravating cireum-stances were improper.
We review a trial court's finding of aggravating cireumstances for an abuse of discretion. Noojin v. State,
Spiller first contends that the trial court erred in finding that the imposition of a reduced sentence would depreciate the seriousness of the crimes as a factor to enhance his sentences. We agree. As our supreme court has noted on many occasions, "this aggravator cannot be used to justify an enhanced sentence. This aggravating factor may be used only when considering the imposition of a sentence of shorter duration than the presumptive sentence." Ector v. State,
Spiller next argues that the trial court abused its discretion in finding his prior criminal history as an aggravating circumstance. He relies on Wooley v. State,
Finally, Spiller contends that the trial court abused its discretion in finding the "great risk" of recidivism as an aggravating cireumstance. The trial court explained this finding "in virtue of the nature of these offenses. These were cold blood
*1275
ed killings. They indicate a total lack of respect for human life." R. at 547. Our supreme court recently addressed a similar claim in Shields v. State,
In sum, although the trial court found one improper aggravating cireumstance, it found three proper ones. These cireum-stances are sufficient to support the enhanced and consecutive sentences imposed. See Willey,
II. Manifestly Unreasonable
As a final point, Spiller contends that his 115-year sentence is manifestly unreasonable. Although this court has the constitutional authority to review and revise sentences, see Ind. Const. Art. VII, § 6, it will do so only when the sentence is "manifestly unreasonable in light of the nature of the offense and the character of the offender." Ind. Appellate Rule 17(B); Redmon v. State,
Oddly enough, Spiller points to Backer v. State,
The mitigating cireamstances regarding Spiller's character (his non-felony criminal history, his admission of guilt, and his cooperation with the prosecution of Jones) pale in comparison to the nature of these multiple, horrific, cold-blooded crimes. Spiller's 115-year sentence is not manifestly unreasonable.
Conclusion
The denial of post-conviction relief is affirmed.
Affirmed.
Notes
. Spiller's "Summary of the Arguments" and "Conclusion" sections of his brief also mention several provisions of the United States and Indiana Constitutions. The body of his argument does not mention these provisions, let alone make a cogent argument as required by Appellate Rule 8.3(A)(7). Accordingly, any claim of error based on these constitutional provisions is waived. Humphrey v. State,
. Although the trial court expressly found the nature of the crimes as an aggravating circumstance at sentencing, it did not mention this factor in its sentencing order. Thus, Spiller contends "[the fact that the trial court deliberately chose not to list the nature and circumstances of the crime as an aggravating factor in the sentencing order precludes consideration of this factor as a basis for imposition of enhanced and consecutive sentences." Brief of Appellant at 17. We disagree. As our supreme court observed in Marshall v. State,
