Police investigated suspected gunfire on the westbound West Seattle Bridge Tuesday evening after a driver reported seeing flashes and hearing popping sounds near the crest of the span.

Additional calls came in from people who reported hearing possible gunshots near the bridge. Police also received a report from someone who had arrived home in South Admiral and found what officers identified as a 9mm casing on a windshield.

The vehicle linked to the incident was described as a dark gray Toyota Prius with plastic covering temporary paper plates. The reporting driver said they exited at Admiral while the other vehicle continued west toward Fauntleroy. No injuries were reported.

By about 6:43 p.m., officers had reported finding casings on the bridge near the crest. Two right lanes were then temporarily closed while police searched the roadway, and officers told dispatch they had found four 9mm casings.
