History
Espinosa was in Spain's gazetteers until Puerto Rico was ceded by Spain in the aftermath of the Spanish–American War under the terms of the Treaty of Paris of 1898 and became an unincorporated territory of the United States. In 1899, the United States Department of War conducted a census of Puerto Rico finding that the population of Espinosa barrio was 787.

Drug trafficking has been an issue in Puerto Rico for many years and in early 1990, $43 million dollars in cash was found buried in plastic barrels, thought to have been deposited by drug smugglers for later retrieval. The sudden wealth of a few residents attracted attention and prompted an investigation by FBI and local police. By May 1990, the FBI had traced $11 million and seized and confiscated property and goods purchased with the money, which was said to belong to drug lord Ramon Torres Gonzalez. FBI stated the money was located on his farm in the Tiburón sector of Espinosa in Dorado and filed charges shortly after.
