A marriage proposal in a Missouri park took a wrong turn when the man dropped to one knee and immediately dropped the $4,000 engagement ring off a bridge.

Staci Dabney posted a video to Facebook showing what was supposed to be Seth Dixon’s romantic proposal to girlfriend Ruth Marie Salas on a wooden bridge at Loose Park in Kansas City, reports UPI.

The video shows Dixon drop to one knee and lose his grip on the engagement ring, causing it to fall through the wooden boards and into the water below.

Dabney’s post shows photos from the aftermath, when the couple’s friends gathered at the bridge to plunge into the water and search for the ring.

‘After a long, hard search all the divers came up empty handed. The couple left with no ring in hand but a heart full of love and memories to last a lifetime,’ Dabney wrote.
