MD: Once DNA was lawfully seized, it can be compared to other samples at will

Defendant’s DNA was lawfully seized in the first place, and it could be compared thereafter to other samples for a match without it being an unreasonable search. The expectation of privacy ceased with the lawful seizure. Varriale v. State, 2015 Md. LEXIS 561 (August 11, 2015). Summary by the court:

The use of a buccal swab inside a person’s cheek to obtain DNA samples for testing is a search. Generally, a DNA sample may be obtained from an individual for testing by consent, pursuant to a warrant, or other court order. If a person’s DNA profile created from a DNA sample is in the lawful possession of the police for examination by consent and does not exceed the scope of the consent given to conduct the search, there is no Fourth Amendment violation. Moreover, the subsequent examination and use of the DNA in an unrelated investigation is not a search. Here, the defendant did not expressly limit the testing and/or use of his DNA. Any legitimate expectation of privacy that Varriale had in the identifying information contained in his DNA obtained from his cheek cells and penile area evaporated when his DNA was lawfully seized; it did not reappear when law enforcement officers compared his DNA sample to other samples and obtained a match.
