� 1 Kenneth White (Appellant) appeals from the judgment of sentence imposed upon him after he pled guilty to aggravated assault and possession of an instrument of crime. The Appellant raises three issues for our review. First, Appellant alleges he was denied the effective assistance of counsel as a result of counsel’s failure to secure a written plea agreement, complete with contingency for withdrawal. The second and central issue suggests the trial court erred in refusing Appellant permission to withdraw his plea. Finally, Appellant questions whether the trial court abused its discretion at sentencing, particularly in light of the mitigating circumstances and public policy considerations at play. We vacate and remand.
� 2 By way of a colloquy, the Appellant admitted the following facts. On the 27 th of December 1999 the Appellant and his cousin, Mr. Charles Cook, were spending the late afternoon at 2211 N. Gratz Street in Philadelphia. At approximately 4:00 P.M., an argument ensued between the Appellant and Mr. Cook. The argument culminated with the Appellant firing four (4) shots from a .38 caliber pistol, one of which struck Mr. Cook in the right knee. Mr. Cook was subsequently treated and released from Temple University Hospital.
� 3 Appellant was subsequently charged with recklessly endangering another person, criminal mischief, making terroristic threats, simple assault, carrying an unlicensed firearm, carrying a firearm in public, aggravated assault, possession of an instrument of crime, and attempted murder. On or about April 10, 2000, the Appellant entered into an “open plea agreement” *fn1 to the charges of aggravated assault, a felony in the first degree, and possession of an instrument of crime, a misdemeanor in the first degree. In exchange, the Commonwealth agreed to demandatorize and defer sentencing. *fn2 After appropriately instructing the Appellant of his rights and determining the submission of the plea was knowing and voluntary, the Honorable Sheldon C. Jelin accepted the plea. As per the terms set forth in the written guilty plea colloquy, Judge Jelin deferred sentencing and defense counsel waived Pa.R.Crim.P. 1405. Also, as contemplated by Appellant and the ADA, Appellant provided substantial information regarding open homicide cases.
