A Chicago singer who appeared in the Mexican version of "The Voice" in 2011 died Saturday after being shot in an ambush outside his Tras Bambalinas School on Chicago’s Southwest Side. The incident, which occurred Thursday, comes amid several other unrelated shooting incidents in the city over the weekend in which at least 18 people were shot.

Alejandro “Jano” Fuentes was shot three times in the head late Thursday, the Cook County Medical Examiner's office confirmed, the Associated Press reported. The 45-year-old got into his car with his friends after celebrating his birthday when an armed man suddenly ordered the singer out of the vehicle and shot him.

The death of Fuentes comes just a week after Christina Grimmie, who appeared on the American version of “The Voice,” was shot to death apparently by a deranged fan as she signed autographs after a performance in Orlando, Florida. The suspect in the case killed himself after shooting Grimmie.

In Fuentes' case, police reportedly said that they had no suspects, but an investigation is underway to determine whether the shooting was an attempted carjacking or a robbery.

Meanwhile, six of the 18 people who were shot in the other shooting incidents in Chicago have died.
