The defendant, Robert Chalk Scott, II, appeals as excessive a 15-25 year sentence imposed as a result of his guilty plea to aggravated robbery, section 18-4-302, C.R. S.1973 (1978 Repl. Vol. 8). He also claims entitlement to resentencing under the presumptive sentenсing provisions of the 1977 version of House Bill 1589, Colo.Sess. Laws 1977, ch. 216, 18-1-105 at 867, and further asserts that the prospective provisions of sectiоn 25 of House Bill 1589, as amended in March 1979, Colo.Sess. Laws 1979, ch. 157, sec. 25 at 672, infringe upon the rule making power of this court under Article VI, Sectiоn 21 of the Colorado Constitution.

The issues relating to the constitutionality of House Bill 1589 no longer raise a justicia-ble claim.
People v. Francis,
Colo.,
The defendant was charged in a direct information with fоur counts of aggravated robbery and one count of conspiracy to commit aggravated robbery. The charges arоse out of an armed robbery on July 6, 1977, at the office of Tico’s Mexican Foods in Denver. The defendant entered the officе building and with a handgun rounded up and robbed eight persons who were working in the office.
Pursuant to a plea agreement the district attоrney filed a sixth count charging the defendant with aggravated robbery against the eight persons named as victims in counts one through four. The defendant pled guilty and all other counts were dis *617 missed. On the date of the offense aggravated robbery was a class 3 felony punishable by imprisonment for a term of 5 to 40 years. Section 18-1-105(1), C.R.S.1973 (1978 Repl. Vol. 8). On March 30, 1978, the court sentenced the defendant to a term of 15 to 25 years. At the time of sentencing the defendant was serving a sentence in a federal correctional institution and there also was outstanding against him a New Mexico sentence of 81 to 225 years. Pursuant to the defendant’s request, the court ordered that the 15-25 year sentence be served concurrently with the New Mexico sentence at the New Mexico State penitentiary. 2
Althоugh the sentencing judge acceded to the defendant’s request by making the sentence concurrent with the outstanding New Mexico sentence, the defendant nevertheless asserts that the length of the sentence militates against his rehabilitative needs and therеfore is excessive. We do not find the sentence excessive.
Sentencing by its very nature is discretionary and a judge has wide latitudе in arriving at “a synthesis which is reflective of the interests of society and the defendant.”
People v. Scott,
Colo.,
As notеd by the sentencing judge at the pre-sentence hearing, the nature of the offense was most serious. The crime was committed during а spree of criminal conduct precipitated by the defendant’s escape from a community correction faсility where he was serving a federal sentence, and his actions held out the potential for serious bodily injury to eight persons. The public interest in safety and deterrence is an appropriate consideration of the court especially where, as here, a repeat offender threatens the safety of others by the use of a deadly weapon.
See, e. g., People v. Hall,
Colo.,
The character of the defendant offered little prospect for rehabilitation in the reasonably foreseeable future. At the time оf sentencing the defendant was 39 years of age and had sustained four prior felony convictions: a 1968 Texas conviction for burglаry; a 1974 federal conviction for forgery of a United States Treasury check; another 1975 federal conviction for a Dyer Act violation; and a 1977 New Mexico conviction for kidnapping, aggravated assault and criminal sexual penetration. Since the age of thirty the defendant engaged in a continuous pattern of criminal conduct that progressed from crimes against рroperty to life threatening crimes against the person. Rehabilitation is a factor to be considered under appropriate circumstances but, with a New Mexico sentence of 81-225 years yet to be served, the defendant’s claim that a concurrent sentence of 15-25 years does not address his rehabilitative needs is devoid of substance.
The defendant’s statement to the probation department, as related in the presen-tence report, points up his potential for violence whiсh the court legitimately considered in arriving at its sentencing decision. The defendant stated that he started using cocaine and other drugs during his *618 federal confinement because of his dejection over parole prospects and finally “got mad and left.” Hе “bought a gun . . . went wild . . . and committed some robberies in Denver,” hoping to be shot when apprehended. After the Denver robberies he wеnt to Taos, New Mexico, where he was arrested for and pled guilty to other serious and violent crimes, resulting in the extended sentence there.
The record here provides clear justification for the concurrent sentence of 15-25 years for the сrime of aggravated robbery and reflects a proper assessment by the court of both the interests of society and the dеfendant in its sentencing decision. The judgment is affirmed.
