The number of murder investigations in Mexico rose to a record high in May, official data showed, as criminal violence increased dramatically since last year.
There were 2,186 murder probes in May, the highest for any month in data going back to 1997, according to the latest government statistics.
Some cases may include multiple homicides, and the number of murder victims reported in May was 2,452, the highest for any month in a separate series of data that only goes back to 2014.
The violence has contributed to a slump in the popularity of President Enrique Pena Nieto, and could undermine support for his Institutional Revolutionary Party in next year’s presidential race. Mexican presidents can only serve one six-year term.
