Cayetano Santos Godino (October 31, 1896 – November 15, 1944), also known as El Petiso Orejudo ("the big-eared midget"), was an Argentine serial killer who terrorized Buenos Aires at age 16.

His father and mother, Fiore Godino and Lucia Ruffo, were Italians who chose to disembark in Argentina hoping to improve their life but they were abusive alcoholics.

A police officer intervened, but Cayetano was released from jail due to his young age.

However, a missing-persons complaint dated 29 March 1906 of a three-year-old girl named Maria Rosa Face was filed at the 10th police station.

A month and a half later, on March 7, 1912, Cayetano set fire to the dress of 5-year-old Reyna Vainicoff, who did not recover and died some days later.

On November 16, 1912, he assaulted three-year-old Carmen Ghittoni, who suffered minor wounds before a police officer intervened, and Cayetano ran off.

[citation needed] On December 3, 1912, Cayetano saw 3-year-old Jesualdo Giordano playing outside his house and offered to buy the boy some sweets to convince him to go with him.

Because medical reports declared him insane, the judge discontinued the case and ordered him to stay in the reformatory.

From 1935 onwards, he was always ill and received no visitors until he died on November 15, 1944, under suspicious circumstances, There was, however, much speculation that his death was due to internal bleeding caused by a gastrous outbreak.

When the prison was torn down and authorities were digging up the remains of dead inmates, his bones were mysteriously missing.
