In this appeal from the Superior Court, we consider whether a warrantless search of a probationer’s person and residence, conducted by State probation officers, was proper. We conclude that, given the circumstances surrounding the defendant’s confrontation with probation officers, the officers had probable cause to conduct the search and the Superior Court correctly concluded that the drugs subsequently seized from the defendant should not have been suppressed. Accordingly, we affirm.
I.
On March 14, 1997, the appellant, Curtis McAlister (“McAllister”), was arrested on drug charges following a search of the Wilmington home in which he resided. On that date, shortly' after 9:00 a.m., Gregory Morehart (“Morehart”), a probation officer with the Delaware Department of Correction, received a telephone tip from a confidential informant that illegal drugs could be found in a padlocked bedroom at the residence shared by two probationers, Norma Johnson and Curtis McAlister. The informant had previously provided Morehart with similar information, but was not one of his probationers. At the time, both Johnson and McAlister were serving a term of probation for previous convictions of drug offenses.
*1122 After receiving the tip, Morehart proceeded to a previously scheduled event and did not return to his office until midday. When he returned, Morehart called Johnson, whom he was assigned to supervise, and informed her that he wanted to make a home visit. Johnson told Morehart that she was about to leave, but would wait for Morehart to arrive. McAllister’s assigned probation officer was not working that day. Before going to the Johnson residence, Morehart attempted to reach Thomas Scully, a higher ranking probation officer who also supervised McAllister’s probation officer. Scully was out of the office, however, and could not be reached.
Morehart was concerned that Johnson would not continue to wait for him, so he requested the assistance of three other probation officers to accompany him immediately to the Johnson residence. More-hart asked Scully’s secretary to continue to try to contact Scully, and informed her where he and the other officers were going. When they arrived at the Johnson residence, Johnson allowed the probation officers into the house. Morehart explained that he had received information that there were drugs in a padlocked room. Johnson acknowledged that one room was padlocked, but that McAllister occupied the room and she did not have a key. While the officers were speaking with Johnson, Morehart saw McAllister’s car pull up outside. Morehart went out to meet McAllister and escorted him inside. Without administering a Miranda warning, Morehart questioned McAllister about the allegations made by the informant. McAllister admitted that he had a key to the padlocked room and that he sometimes slept there. When Morehart informed McAllister that he intended to search the room in order to determine the validity of the allegation, McAllister became agitated and attempted to flee the residence. The probation officers restrained and handcuffed McAllister. The officers then conducted a search of McAllister’s person and found a large bundle of cash in his pocket, as well as a set of keys. The Wilmington police were called to assist the probation officers.
At this point, one of the probation officers, Mark Herron, finally spoke with Scully, who had called the residence. After describing the circumstances leading up to that point in time, Scully authorized the probation officers to search McAllis-ter’s room. Using a key obtained from McAllister, Morehart and Herron entered the room and saw what appeared to be drugs lying on the bed. The probation officers left the room and informed the police of their discovery. McAllister and Johnson were taken into custody and, after obtaining a search warrant, the police confiscated the contraband from McAllister’s room.
Prior to his trial on the drug charges, McAllister filed a motion to suppress the contraband and the statements he made to Morehart, alleging that the evidence was obtained in violation of his constitutional rights. The trial court denied that motion, and the case proceeded to trial. A jury found McAllister guilty of trafficking in heroin, possession with intent to deliver heroin, maintaining a dwelling for the use or consumption of narcotics, conspiracy in the second degree, and possession of drug paraphernalia. This appeal followed.
II.
McAllister challenges the trial court’s refusal to suppress evidence seized from his person and room, as well as statements he made to the probation officers upon initial questioning. This Court reviews the trial court’s denial of a motion to suppress, after an evidentiary hearing, under an abuse of discretion standard.
Liu
*1123
v. State,
Initially, we dispose of McAllister’s claim that the trial court used an incorrect legal standard in ruling on his motion to suppress. The State concedes that the trial court improperly placed the burden on McAllister to establish that his Fourth Amendment rights had been violated by the challenged search.
See Vale v. Louisiana,
McAllister mounts a broad-ranging attack upon the constitutionality of the statutory authority exercised by probation officers and the specific conduct of the officer who confronted McAllister at the time of his arrest. The legislative authority permitting probation officers to effect searches of the individuals they supervise is found in 11 Del. C. § 4321. The Department of Correction has, pursuant to that authority, adopted regulations regarding warrantless searches of probationers. Those regulations provide that, prior to a personal search or a living quarters search, the probation officer and the supervisor “shall have a case conference” and “[t]he Pre-Search Checklist should be used as a guideline unless emergency circumstances dictate otherwise.” Dept, of Correction Procedure 7.18. Further, “before any search is conducted, Officers must first have the approval of a supervisor or designee, unless emergency circumstances dictate otherwise.” Dept, of Correction Procedure 7.19. There is no dispute that Morehart did not have a case conference with a supervisor before proceeding to the Johnson residence, nor did he complete a pre-search checklist. Morehart testified, however, that he did consider the elements of the checklist “in his mind” before deciding to search. Supervisory approval for a search was obtained before the search of McAllister’s room.
III.
The search in this case was conducted by probation officers, acting in their official capacity as supervisors of Johnson and McAllister’s probation.
See
11
Del. C.
§ 4321(d)
*
(authorizing proba
*1124
tion officers to conduct searches of individuals under probation supervision in the performance of the lawful duties of their employment). As the United States Supreme Court has observed, “inherent in the very nature of probation is that probationers do not enjoy the absolute liberty to which every citizen is entitled.”
Griffin v. Wisconsin,
Once lawfully present in the Johnson residence, the probation officers were able to corroborate the tip Morehart received. Johnson confirmed that there was a padlocked bedroom in the house and that it was occupied by McAllister. It is at this point, after the independent corroboration of a tip from a confidential informant, that McAllister’s first contact with the officers occurred. An informant’s tip that is corroborated by independent police work can form the basis for probable cause, regardless of what is known about the informant’s personal credibility or reliability.
Tatman v. State,
When McAllister arrived at the residence, which was presumably McAllister’s intended destination, Morehart went outside to meet him. Morehart identified himself to McAllister (whom he had met previously), indicated that he was interested in speaking with McAllister, and escorted McAllister inside. Once inside, McAllister was informed of the tip received by Morehart. McAllister acknowledged that he sometimes slept in the padlocked room and that he had a key. Morehart told McAllister that he wished to search the room in order to verify the validity of the tip. It was at that point that McAllister attempted to flee and was detained by the probation officers.
WTien McAllister attempted to flee, the probation officers had a right to detain him, because probable cause existed to believe that McAllister was in violation of his probation.
See Woody v. State,
Having lawfully retrieved a key to the padlocked room from McAllister’s pocket, the probation officers then used the key to enter his room. Before doing so, the probation officers obtained permission from a supervisor, who verified that the circumstances justified the intended search. Given the totality of the circumstances, including McAllister’s status as a probationer and his limited privacy rights resulting therefrom, the officers’ use of the key to open the locked door was reasonable and did not contravene the Fourth Amendment or Article I, § 6 of the Delaware Constitution.
See U.S. v. Knights,
Although we affirm the trial court’s denial of McAllister’s motion to suppress in this case, we note that probation officers are not sworn police officers, and are’subject to constraints that do not apply to police officers. Probation officers have authority to detain probationers and execute searches of their persons or property only to the extent granted them by the General Assembly. Particularly when conducting warrantless searches, probation officers may act only pursuant to explicit statutory authority. While the conduct of the probation officers in this case was haphazard and uncoordinated, they did not overstep their supervisory authority over a person who continued under the control of the Department of Correction.
Because we find that the search conducted by the probation officers was reasonable and supported by probable cause, we need not address McAllister’s claim that 11
Del.
C. § 4321(d), and the accompanying Department of Correction regulations, are unconstitutional.
See DeShields v. State,
We emphasize that this case does not implicate questions of whether probation officers can exercise the general constitutional power granted to police officers. The case is unique because: (i) the officers were on the premises with the consent of the property owner who was also subject to visitation as a probationer; (ii) the probation officers’ contact with McAllister was non-confrontational until McAllister attempted to flee; and (iii) the probation officers possessed reliable and verified information "about the alleged illegal activities of a probationer before confronting the probationer.
IV.
McAllister also claims that Morehart’s failure to administer
Miranda
warnings before questioning him required the suppression of his inculpatory statement admitting that the room was his.
Miranda
warnings are required only
*1126
where (1) questioning of a suspect rises to the level of interrogation and (2) the interrogation occurs while the suspect is either in “custody” or in a “custodial setting.”
Marine v. State,
“In order for a court to conclude that a suspect is in custody, it must be evident that, under the totality of the circumstances, a reasonable man in the suspect’s position would feel a restraint on his freedom of movement fairly characterized as that ‘degree associated with formal arrest’ to such an extent that he would not feel free to leave.”
Torres v. State,
V.
Finally, McAllister objects to the introduction of Johnson’s statement to Morehart acknowledging that the padlocked room belonged to McAllister. We review evidentiary decisions by the trial court under .an abuse of discretion standard.
Jones v. State,
Johnson was a reluctant State witness and, on direct examination, denied that McAllister had a key to the room. The State then asked Johnson, as permitted by 11 Del. C. § 3507, whether she had originally told Morehart that McAllister had a key to the bedroom. Johnson replied that she did not remember. More-hart was then called to the stand and questioned about what Johnson had told him. Morehart testified that Johnson stated that McAllister stayed in the padlocked room. McAllister objected because Johnson had been questioned only about possession of the key to the room, not its occupancy. The trial court withheld decision on the motion, giving the State an opportunity to recall Johnson to clarify. The State decided not to recall Johnson, however. Once the State indicated that it did not intend to recall Johnson, McAllis-ter requested, and received, a curative instruction advising the jury to disregard any testimony that was the subject of a valid objection.
McAllister argues that this instruction was not specific enough to cure the error. The State argues that any error was harmless because the fact that M'cAllister stayed in the room had already been established by other testimony. We agree *1127 that the trial court’s instruction was sufficient to cure the defect and that, in any event, any error was harmless beyond a reasonable doubt because the evidence solicited was merely cumulative. DeAngelo v. State, 795 A.2d 667 (Del.2002).
The judgment of the Superior Court is AFFIRMED.
Notes
11 Del. C. § 4321(d), in its entirety, provides:
Probation and parole officers shall exercise the same powers as constables under the laws of this State and may conduct searches of individuals under probation and parole supervision in accordance with Department procedures while in the performance of the lawful duties of their employment and shall execute lawful orders, warrants and other process as directed to the *1124 officer by any court, judge or Board of Parole of this State; however, a probation and parole officer shall only have such power and duties if the officer participates in and/or meets the minimum requirements of such training and education deemed necessary by the Department and Board of Examiners.
