Heloísa Gonçalves Duque Soares Ribeiro (née Heloísa Borba Gonçalves; born March 13, 1950), known as The Black Widow (), is a Brazilian–American criminal, murderer and accused serial killer. Convicted for the murder of one husband and bigamy/fraud charges in absentia, Gonçalves has been accused in at least three other murders and multiple other violent crimes dating back to 1971, but has so far evaded capture. As of February 2023, she is one of Brazil's most wanted criminals and has a red notice issued for her arrest from Interpol. Early life Due to her tendency to use aliases and not talk about her life, little can be verified about Gonçalves' past. She was born on March 13, 1950, in Porto Alegre, Rio Grande do Sul, as Heloísa Borba Gonçalves, and had her first child at age 19 with then-boyfriend Carlos Pinto da Silva.

On that date Pinto was shot five times in the chest, but managed to survive and identified the assailant as Gonçalves. For reasons unknown, he decided to withdraw the complaint for attempted murder and the case was dropped. In 1980 Gonçalves was arrested on fraud charges for signing a document under the name "Matilde Irene Gomes da Silva". Unwilling to be imprisoned again, from then on she would legally adopt her future husbands surnames to avoid trouble. A year after this, she began a relationship with security guard Irineu Duque Soares and had a child with him that same year, but the pair did not officially marry until May 13, 1983. In October of that year, the family
