For the first time in 20 years, Blue Island Mayor Donald Peloquin is facing two challengers in an election influenced by the controversial death of a Mexican-American immigrant last year. Antonio Manrique, 74, died Oct. 10, four days after he was tackled to the ground by a police officer responding to a call about graffiti. The incident, which is under investigation, outraged and united the Hispanic community, ultimately fueling a desire to have more influence in city government. As a result, the April 5 ballot includes more Hispanic surnames than any other in recent memory. The election also includes several members of CASA, or Citizens in Action Seeking Answers, a grass-roots community group formed in response to Manrique's death. "The incident brought to light the need for more community participation at all levels," said Rene Valenciano, principal of a local elementary school who is running for 5th Ward alderman. "We want more accountability overall."
