A New York farm worker will receive a 20-year prison sentence in the 2018 deaths of his girlfriend and her 1-year-old boy, officials said.

According to WHAM-TV, 27-year-old Alberto Ebarado Gutierre-Reyes, aka Everardo Donoteo-Reyes, of Mexico, pleaded guilty to first-degree manslaughter charges under a deal accepted last week, attorneys said. His sentencing is set for Nov. 7, the Rochester Democrat & Chronicle reported.

Gutierre-Reyes, of Mexico, originally faced second-degree murder charges in the deaths of Selena Hidalgo-Calderon, 18, and her son, Owen, WHAM reported. The mother and son vanished in May 2018, prompting a massive, multi-day search in Sodus.

Crews later discovered their remains at Joy Road farm, where Gutierre-Reyes and Hidalgo-Calderon shared a home and worked, according to the Democrat & Chronicle.

Authorities have not revealed how Hidalgo-Calderon and her son died, the news outlets reported.
