delivered the Opinion of the Court.
K. M. H., a youth, appeals an order of the Tenth Judicial District Youth Court, Fergus County, waiving jurisdiction and transferring K.M.H. from Youth Court to District Court. The Youth Court’s order was based on a December 4, 1986, petition alleging that K.M.H. is a delinquent youth and alleging that K.M.H. committed deliberate homicide and attempted deliberate homicide.
We affirm.
The sole issue on appeal is whether the Youth Court abused its discretion when it transferred K.M.H. to District Court pursuant to Section 41-5-206, MCA (1985)?
After careful review of the record, we hold the Youth Court did not abuse its discretion when it transferred K.M.H. to District Court. However, in order to protect appellant’s right to a fair trial, we decline to detail the evidence produced at the transfer hearing. Additionally, we decline to name witnesses testifying at the May 11, 1987, transfer hearing.
At the May 11, 1987, transfer hearing, two of the State’s witnesses, S.F. and John Moffatt made the following allegations. On the morning of December 4, 1986, K.M.H. brought a .41 magnum revolver to *182Fergus County High School. At approximately 1:17 p.m. on the same day, K.M.H. shot and killed a substitute French teacher, Henrietta Smith. Moments later, K.M.H. shot and seriously injured assistant principal John Moffatt. As Moffat lay wounded on the floor, K.M.H. fired again and missed.
On December 4, 1986, a petition was filed alleging that K.M.H. is a delinquent youth and alleging that he committed deliberate homicide and attempted deliberate homicide. Subsequent to filing the petition, appellant was sent to Rivendell, formerly the Montana Youth Treatment Center, for a psychiatric evaluation. He was then enrolled in Pine Hills School for Boys.
On December 8, 1986, respondent moved to transfer the matter ■from Youth Court to District Court pursuant to Section 41-5-206, MCA (1985). Section 41-5-206, MCA (1985),1 provides in pertinent part:
“(1) After a petition has been filed alleging delinquency, the court may, upon motion of the county attorney, before hearing the petition on its merits, transfer the matter of prosecution to the district court if:
“(a)(i) the youth charged was 12 years of age or more at the time of the conduct alleged to be unlawful and the unlawful act would constitute sexual intercourse without consent as defined in 45-5-503, deliberate homicide as defined in 45-5-102, or mitigated deliberate homicide as defined in 45-5-103, or the attempt, as defined in 45-4-103, of either deliberate or mitigated deliberate homicide if the act had been committed by an adult . . . [and]
“(d) the court finds upon the hearing of all relevant evidence that there are reasonable grounds to believe that:
“(i) the youth committed the delinquent act alleged;
“(ii) the seriousness of the offense and the protection of the community require treatment of the youth beyond that afforded by juvenile facilities; and
“(iii) the alleged offense was committed in an aggressive, violent, or premeditated manner.
“(2) In transferring the matter of prosecution to the district court, the court may also consider the following factors:
“(a) the sophistication and maturity of the youth, determined by consideration of his home, environmental situation, and emotional attitude and pattern of living;
“(b) the record and previous history of the youth, including previ*183ous contacts with the youth court, law enforcement agencies, youth courts in other jurisdictions, prior periods of probation, and prior commitments to juvenile institutions. However, lack of a prior juvenile history with youth courts will not of itself be grounds for denying the transfer.
“(c) the severity of the offense;
“(d) the prospects for adequate protection of the'public and the likelihood of reasonable rehabilitation of the youth by the use of procedures, services, and facilities currently available to the youth court. [Emphasis added.]”
Appellant K.M.H. contends the District Court abused its discretion when it found: (1) reasonable grounds to believe that the seriousness of the offense and the protection of the community require treatment of the youth beyond that afforded by juvenile facilities; and (2) reasonable grounds to believe the alleged offenses were committed in an aggressive, violent or premeditated manner.
Our standard when reviewing juvenile transfer proceedings is to determine whether the Youth Court abused its discretion by failing to consider all statutory criteria and whether substantial credible evidence supports the Youth Court’s finding that juvenile facilities are inadequate in light of the “seriousness of the offense and the need to protect the community.” Matter of B.D.C. (Mont. 1984), [211 Mont. 216,] 687 P.2d 655, 658, 41 St.Rep. 1318. The youth may not be transferred simply because he has committed a serious offense. In re Stevenson (1975), 167 Mont. 220, 538 P.2d 5, 9.
A review of the record supports the findings, conclusions and order of the Youth Court. At the May 11, 1987, transfer hearing, the testimony of K.D. and M.R. corroborated the assertions of S.F. that appellant knocked on the French classroom door and shot Henrietta Smith. This testimony, coupled with John Moffatt’s testimony, constitutes reasonable grounds to believe that K.M.H. committed the crimes. The crimes, attempted deliberate homicide and deliberate homicide, are serious offenses. Matter of N.C.F. (Mont. 1982), 197 Mont. 390, 643 P.2d 236, 238.
Dr. H.S.N., medical director at Rivendell, testified that appellant suffers from schizotypal personality with a mild dysthymic disorder. He recommended that appellant live in a structured environment and receive treatment for several years. Additionally, Dr. H.S.N. stated that if appellant were faced with another stressful situation, another explosive reaction might occur.
A.D., superintendent of Pine Hills School for Boys, testified that *184Pine Hills is not an appropriate place to treat a “psychologically impaired youth who committed a homicide.” D.D.R., administrator of the Division of Corrections, Department of Institutions, testified by deposition that if appellant was not transferred to District Court, the Department of Institutions would lose all jurisdiction to treat and supervise him when he reaches age 21. M.F.O., chief probation officer for the Tenth Judicial District, testified that he felt appellant should be transferred to the adult system to allow adequate supervision for a significant number of years.
The Youth Court, in its findings and conclusions, indicated that appellant could not be properly supervised and treated if he remained under jurisdiction of the Youth Court:
“In summary, the most critical factor herein is the prospect for adequate protection of the public and the likelehood [sic] of reasonable rehabilitations of [K.M.H.] by use of procedures, services, and facilities currently available to the Youth Court. This Court cannot conclude with reasonable certainty that [K.M.H.] will not require supervision and possible further treatment after he reaches the age of 21 years. The Youth Court loses all jurisdiction and control of the youth at age 21. On the other hand, if the youth is transferred into the adult criminal Court there will be more options available for treatment (possible psychiatric treatment at Warm Springs State Hospital) and supervision (as Swan River Forest Camp, a Half-Way House, or Montana State Prison, or on probation or parole for a longer period of time). [Emphasis added.]”
We hold that substantial credible evidence supports the Youth Court’s finding that K.M.H. be transferred to District Court in light of the seriousness of the offenses and the need to protect the community.
Appellant also contends that substantial credible evidence does not support the Youth Court’s finding the alleged offenses were committed in an aggressive, violent or premeditated manner. We do not agree.
The assertions of S.F. support the Youth Court’s finding that appellant allegedly planned the shooting several days prior to the commission of the crimes. Appellant’s alleged conduct constitutes aggressive, violent and premeditated execution of the deliberate homicide and aggressive and violent execution of the attempted deliberate homicide. Section 41-5-206, MCA (1985).
We hold the Youth Court did not abuse its discretion when it *185transferred the above-mentioned cause from Youth Court to District Court.
Affirmed.
