Divers were frantically searching for a 7-month-old baby boy on Monday whose father jumped from the Arrigoni Bridge into the Connecticut River Sunday night in a failed suicide attempt.

Police issued a Silver Alert for Aaden Moreno, who was last seen wearing black pants and a white shirt with black stripes and a Mickey Mouse picture on it. The little boy is 2-feet tall and weighs 23 pounds. He has big brown eyes and brown hair.

Authorities say his father, Tony Moreno, 22, called someone around 11:35 p.m. on Sunday night and threatened to commit suicide. The person Moreno called contacted police to report Moreno’s behavior and threat to jump from the steel arch bridge into the Connecticut River.

The caller who reported Moreno's suicidal behavior also reported hearing Aaden in the background while the two were on the phone.

Officers responding to the scene Sunday night said they believe the baby was with Moreno, but did not actually see the child. They did see Moreno jump into the water.

Middletown firefighters rescued Moreno from the river. He was airlifted to Hartford Hospital, where he is listed in serious condition.

Police also are looking into the possibility Moreno threw his son into the river before he jumped. They are checking with friends and family to see if he dropped the baby off somewhere else. Middletown Mayor Daniel Drew told the Hartford Courant, “There are a number of other sites the police department is searching… including public places, because they want to leave nothing to chance.”

Drew added that authorities would “devote every available resource to the search” and said he prays they will find the baby safely.

So far, three fire departments, two police agencies and the state Department of Energy and Environmental Protection are involved in the investigation. The Middletown Police Department, the fire departments and the state police dive team are also involved.
