Soto also studied at Puerto Rico Junior College, completing a degree in Criminology.

He also completed an associate degree in Economy and Physical Education from the Interamerican University of Puerto Rico.

He beat candidates Estéban Meléndez (PPD) and Eduardo Betancourt (PIP) to win the seat.

However, the next year, Soto announced he would aspire to a seat in the Senate of Puerto Rico,[7] but he was defeated in the 2016 primaries.

One of his daughters, Lornna Soto, was a Puerto Rican Senator and eventually succeeded him as mayor of Canóvanas.
