Commonwealth v. Garvin

Summary

The Supreme Court of Pennsylvania held that the warrantless arrest of Benjamin Garvin was illegal because the arresting officer lacked sufficient information to establish probable cause. The court nevertheless upheld the admission of identification evidence, concluding that the illegal arrest merely hastened an inevitable confrontation and did not taint the identifications; it also upheld nondisclosure of the informant's identity and the trial judge's credibility determination.

Holdings

1. The arrest was illegal because the officer lacked sufficient information to independently assess the reliability of the information relayed through the informant.
2. The identifications were not required to be suppressed because the illegal arrest merely hastened an inevitable confrontation and did not exploit the illegality or influence the witnesses' knowledge or the accuracy of their identifications.
3. Disclosure of the informant's identity was not required because the informant's testimony was not crucial and the victims provided positive, independent identifications.
4. The trial judge, sitting as factfinder, had exclusive authority to assess the accomplice's credibility, and the credibility determination was not manifestly erroneous.

Questions Presented

1. Whether Garvin's warrantless arrest was supported by probable cause.
2. If the arrest was illegal, whether the ensuing identification evidence was tainted and subject to suppression under the exclusionary rule.
3. Whether the trial court erred by permitting the Commonwealth to withhold the identity of the informant.
4. Whether the trial judge's rejection of accomplice Thomas Leging's exculpatory testimony was manifestly erroneous.

Disposition

affirmed
