Authorities in Connecticut say a Monroe man survived a harrowing murder attempt when he was thrown off of a bridge.

The 30-year-old victim reportedly plunged nearly five stories to the frigid water below the Derby-Shelton Bridge.

Police were able to rescue him from the water and have arrested three suspects in connection with the crime.

According to the Connecticut Post, 25-year-old Gregory Rottjer, of Derby, faces charges of attempted murder, first-degree assault and reckless endangerment.

Two others, 27-year-old Matthew Dorso and 22-year-old Jennifer Hannum, face lesser charges.

Police believe Rottjer and Hannum, a couple, were on the bridge arguing when the victim and his brother intervened to check on Hannum’s welfare.

Rottjer and Dorso reportedly responded with force, engaging in a physical altercation with the two men that ended when Rottjer intentionally threw the victim over the bridge’s railing.

Police say he admitted his role in the crime during an interview with investigators.

“I did it,” he reportedly said. “I threw him over the bridge.”

Investigators collected other evidence against Rottjer, including cellphone images and video footage showing the altercation.

He was arrested and jailed with bail set at $250,000.

Hannum faces a charge of interfering with an officer. Reports indicate investigators found her statement to be inaccurate. She was arrested and released after posting $1,000 bail.

Dorso, who allegedly fled the scene with Rottjer after the crime, is charged with third-degree assault. He was released from custody after promising to appear in court.
