Three young children found dead on a New York beach were allegedly drowned by their mother. 

Police say 30-year-old Erin Merdy reportedly confessed to the murders. A 90-minute search was launched early Monday after several of Merdy's relatives called police, concerned that Merdy may have done something to her children. 

The children ages, 7, 4, and 3 months, were found lying in the sand. Merdy, meanwhile,  was nearly two miles away on the Brighton Beach boardwalk.

Merdy was soaking wet, barefoot,  and walking in her bathrobe. Speculation is that Merdy may have been drinking or suffering postpartum depression. No confirmation of either has yet been made.
