Ryan Lawrence has pleaded guilty to murdering his 21-month-old daughter in February.

The Syracuse man – who beat Maddox Lawrence to death at Labrador Hollow and then dumped her body in Onondaga Creek – pleaded guilty to first and second-degree murder on Thursday.

His sentences will be served concurrently.

He also waived his right to an appeal.

Lawrence is scheduled to be sentenced on Oct. 7.

Morgan Lawrence – the child’s mother – was in court when Ryan Lawrence pleaded guilty.

The baby’s body was found lying in the water near the Inner Harbor.

An Amber Alert was issued the morning after Ryan and Maddox Lawrence disappeared from their Valley neighborhood home on Saturday, Feb. 20.

Morgan Lawrence contacted police after she found their family car in the Destiny USA parking lot and drove home – where she discovered a message from Ryan.

The contents of the message alarmed police when they responded to the home.

Ryan Lawrence was picked up by police in the village of Baldwinsville the following Monday.
