Authorities in Mexico City have conducted separate investigations into criminal activities involving different victim groups.

In the Historic Center, police arrested Lucía García Pérez, who allegedly targeted an elderly man by using a chocolate bar to deliver sleep inducing medication to facilitate theft. This incident has prompted investigations into potential patterns of similar crimes against senior citizens.

In the Condesa neighborhood and Parque España, a 58-year-old man, identified as Salvador “N”, was arrested for allegedly poisoning dogs with methomyl, a highly toxic insecticide, concealed in meat products. The investigation follows the deaths of at least four dogs and reports of several others becoming intoxicated after consuming baits containing blue capsules. Forensic analysis by the Mexico City Prosecutor's Office (FGJ-CDMX) confirmed the baits consisted of meat products such as salami and chorizo. Authorities recovered between 14 and 16 contaminated baits during the investigation.

Preliminary findings suggest the motive may have been retaliation for a previous dog attack involving a family member of the suspect. The individual was apprehended on October 30 near the intersection of Atlixco and Juan Escutia streets after being identified through surveillance footage. According to the Secretariat of Citizen Security (SSC), the suspect reportedly insulted and physically assaulted police officers during his arrest. He faces potential charges related to animal cruelty or mistreatment.
