Pedro Yanez, 39, was killed in a drive-by shooting in the early hours of February 12, 2018, at a house on East Marshall Street in Tulsa, Oklahoma. According to investigators, a vehicle pulled up and sprayed the home with gunfire; Yanez was struck and later died. He was identified as a Hispanic male and known by the nickname Spider.

The investigation tied Yanez to gang and drug activity. He was said to be a member of South Side Lokos 13, a Sureño-affiliated group with links to the Mexican Mafia. Police described ongoing rivalries involving the Florencia and Latin Kings as part of a violent dispute over control of the local drug trade. Earlier the same evening Yanez had been in an argument with a man who briefly left, returned to try to force entry, broke a window, and left again before the shooting.

Investigators named a primary suspect, Ibara Pelgrren, after finding a wallet and a birth certificate at the scene. Authorities later charged Jose Pelgrren with first-degree murder; he was not apprehended and is believed to have fled. Officers also suspected multiple shooters. The identities of any other participants remain unknown and the case remains unresolved. Have any readers with knowledge of Yanez, the people present that night, or the Pelgrren name come forward with information?
