Commonwealth v. Rogersgreen1 sentence2013Cf. Commonwealth v. Lopez, supra (in nonemergency situation, police seeking hotel manager did not gain legal consent to enter from woman not known to police and whose relationship to premises was uncertain); Commonwealth v. Rogers, supra at 239, 241 (ambiguity regarding consent to enter premises existed where officers who arrived unannounced and did not identify themselves asked where they could find defendant, and person who answered their inquiry pointed inside). b. | 1 | 1 |
