Sheriff promises Florida vigil attendees: Politicians 'will not get re-elected' if gun laws don't change Members of the audience cried as prayers were read for the victims and families.

 -- Hundreds of people attended vigils remembering the 17 victims who were killed in a school shooting in Parkland, Florida on Wednesday, with the sheriff responsible for overseeing the case telling attendees at an evening gathering that gun laws must be fixed.

Broward County Sheriff Scott Israel made pointed comments on gun control, saying, "If you are an elected official and you want to keep things the way they are and not do things differently, if you wanna keep the gun laws as they are now -- you will not get re-elected in Broward County."

The statements receiving a round of applause and standing ovation from the crowd.

Several speakers took to an elevated stage to pray for those who died, the injured who are recovering in the hospital and the first responders and school staff who worked so valiantly to keep them safe.

"We mourn for the potential that was lost -- for the hopes, for the joys, for the dreams that will never be realized," one speaker said of the young victims and the heroes who died while protecting the students.

Nearly every seat in the outdoor auditorium was filled, with an audience so large that it spilled onto the sidewalk on the other side of the fence separating the area.

Some members of the crowd nodded silently, while others cried with their hands buried in their faces, as numerous prayers were read.

Earlier in the day, 17 balloons were released during a vigil at the Parkland Baptist Church, one for each who was killed.

Multiple students were in attendance at a separate vigil at Parkridge Church in Pompano Beach, showing their support for their fallen classmates by wearing shirts emblazoned with an eagle, the school's mascot.

Later in the evening, a candlelight vigil was held. The vigil lasted about an hour and included a solemn reading of the 17 people who were killed in the shooting.

Among the speakers at the evening event were Chicago Cubs first baseman Anthony Rizzo, who attended Stoneman Douglas High School and graduated in 2007.

"While I don't have all the answers, I know that something has to change, before this is visited on another community, and another community, and another community," Rizzo said.

"We don't know who's hiding their sadness or feelings of guilt and loneliness, or who needs help and is too proud or afraid to ask," he added. "So we have to be there for each other, we have to cope with our pain, and we have to live each other's pain."

On Wednesday afternoon, a former student of Marjory Stoneman Douglas High School, 19-year-old Nikolas Cruz, allegedly opened fire on school campus. In addition to those who died in the attack, more than a dozen people were injured, some critically.

Cruz, who has been charged with 17 counts of premeditated murder, appeared in court Thursday afternoon and is being held in the Broward County Jail without bond.

At the vigil, prayers were read for Cruz and his extended family as well.

"We ask that you would intervene in his disturbed mind and show him the hope that can only be found in you," one speaker asked God, holding back tears. "We pray for your miraculous work to be evident in him, and in spite of him."
