INDIANAPOLIS -- A security guard was killed early Saturday morning as he worked at a private club on Illinois Street.

Robin Lacy, 50, was standing at the club, near the intersection of 33rd and Illinois streets, when an out-of-control SUV barreled toward him, 6News' Renee Jameson reported.

Lacy, a husband and father, was filling in for a friend when he was struck after two SUVs collided.

One of the SUVs hit a telephone pole and crashed into the club. Investigators said the SUV or debris from it struck and killed Lacy.

"He was always trying to just help out and make more money and do anything he could just to support and provide for us," said Gabrielle Lacy, the victim's daughter. "We all knew he loved us a lot and would do anything for us he could."

"I don't think it's right what happened," said Joshua Lacy, the victim's son. "I think there is a little bit more out there that hasn't been said yet."

Indianapolis Metro police are looking for a third vehicle that may have been going the wrong way on Illinois Street or pulled out in front of the SUV, causing the driver to lose control.

The third vehicle was described as a dark, mid-90s box-style vehicle.

"Either a Chevy or Oldsmobile style being driven by a black male with short hair in his 40s," said IMPD Lt. Jeff Duhamell.

Lacy's family said they hope someone with information will come forward so they find out exactly what caused their loved one's death.

"It's just a whole bunch of bits and pieces and stories aren't going together," Gabrielle Lacy said. "I just want everything to come together so I can put it in my head what happened to my father."

People who were in the SUVs were hurt, but their injuries were not life-threatening.

Police asked anyone with information to call Crime Stoppers at 317-262-TIPS.
