Francis Zacher was indicted for conspiracy to distribute methamphetamine, see 21 U.S.C. §§ 841(a)(1), 846, possession of firearms by a user of a controlled substance, see 18 U.S.C. §§ 922(g)(3), 924(a)(2), and possession of an unregistered firearm, see 26 U.S.C. §§ 5861(d), 5871. Before trial, Mr. Zacher moved to suppress evidence that the police had obtained by searching various FedEx packages and his home. The district court 1 denied the motion, Mr. Zacher appealed, and we affirm.
I.
Lenise Jessen, a FedEx employee, was suspicious of the package that Madina Helm had dropped off. Ms. Helm and Mr. Zacher had sent numerous parcels to one Jesse Garcia in recent weeks, and the frequency of these shipments was growing. Ms. Jessen called Detective Cody Trom of the Bismarck, North Dakota, police department to convey her suspicions. Detective Trom decided to investigate and came to the FedEx facility followed shortly by a canine unit.
Once at the facility, Detective Trom took the package from Ms. Jessen and placed it on the floor with several others. The dog alerted to the package, tearing a hole in the cardboard envelope in the process. To confirm the alert, the police had Ms. Jes-sen hide the package, and the dog found it and alerted again.
After the dog alerted the second time, the police called a state’s attorney, who contacted a local magistrate. The magistrate heard sworn testimony from the dog’s handler, Officer Glen Valley, over the telephone and ordered that a warrant be issued. A copy of the search warrant faxed to the FedEx facility was illegible, so an unsigned copy was sent via e-mail to Detective Trom while he was at the FedEx office. The detective gave Ms. Jessen a copy of the warrant and took the package and another copy of the warrant to the magistrate’s home. After the magistrate signed the warrant, Detective Trom returned to the police station, opened the box within the torn envelope, and discovered $5,200 in currency. The police decided *338 to repackage the currency and have it delivered to Mr. Garcia without telling Mr. Zacher, Ms. Helm, or Mr. Garcia of the search and seizure.
II.
Mr. Zacher maintains that the police violated his fourth amendment rights because they did not have reasonable suspicion that the package contained contraband when they seized it. A law enforcement officer must have reasonable suspicion before he or she may seize a package for investigatory purposes.
United States v. Logan,
Everyone agrees that the police seized the FedEx package in question; the pertinent issue is when the seizure occurred. A recent en banc decision of ours governs the determination of when a detention of a package amounts to a seizure for fourth-amendment purposes. In that case, the defendant argued that law enforcement had unlawfully seized his checked luggage. The opinion explains that a seizure occurs only when law enforcement “ ‘meaningfully interfere^]’ ” with an individual’s posses-sory interests in the property.
United States v. Va Lerie,
Mr. Zacher contends first that when the police delayed the timely delivery of the package they lacked sufficient grounds to seize it. The package was supposed to be delivered the next day, and FedEx had to send it out by 6:30 p.m. to meet that deadline. Thus, under
Va Leñe,
a seizure occurred when the police detained the package past 6:30 p.m. By that time, however, the dog had alerted to the package, and we have held that a dog’s positive indication is enough to raise a suspicion sufficient to allow the police to seize a package for further investigation.
See United States v. Graham,
Mr. Zacher points out that it may have been after 6:30 p.m. when the police completed their second test by hiding the package and having the dog search for it. But the mere fact that the officers decided to conduct another test does not mean that reasonable suspicion did not already exist. The question of reasonable suspicion is an objective one, and it exists when there is sufficient information for a reasonable officer to suspect that the package contained contraband or evidence of illegal activity.
See United States v. Payne,
Mr. Zacher argues, in the alternative, that the police wrested custody of the package from FedEx before there was reason to suspect that it contained contraband. We have stated that the sender’s reasonable expectations of how the carrier would handle the package define the scope of the carrier’s custody.
See Va Lerie,
III.
Mr. Zacher also contends that the police violated North Dakota Rule of Criminal Procedure 41(d) by failing to provide him with a copy of the warrant and a receipt detailing what was seized, and that this violation requires that the contents of the package be suppressed. As Mr. Zacher points out, the relevant portion of the state procedural rule is virtually identical to Fed.R.Crim.P. 41(f)(3): Both rules require the police either to “give a copy of the warrant and a receipt for the property taken to the person from whom, or from whose premises, the property was taken; or ... leave a copy of the warrant and receipt at the place where the officer took the property.” N.D. R.Crim. P. 41(d)(2); see Fed.R.Crim.P. 41(f)(3).
Not all violations of this type of rule require the suppression of evidence; we have said that innocent mistakes that do not prejudice the defendant may be excused.
See United States v. Schroeder,
IV.
Two weeks after Ms. Helm dropped off the package, FedEx received a package from Mr. Garcia for delivery to Mr. Zacher. A police dog alerted to this package, and a local judge authorized a search war *340 rant. This time the package contained methamphetamine. Based on this information, Detective Trom asked for and received a warrant to search Mr. Zacher’s residence. That search revealed numerous firearms and other evidence of drug trafficking.
Mr. Zacher argues that because the seizure of his first package was illegal, the district court should have excluded the subsequently discovered evidence. This argument is without merit: Because we have already held that the seizure of the first package did not violate the fourth amendment or involve more than a de minimis violation of North Dakota Rule 41(d), the “fruit of the poisonous tree” doctrine could not apply to any subsequent evidence that the police discovered.
Affirmed.
