abductor alongside Interstate 490 had attempted to offer her any assistance generated intense public outrage. Two New York newspapers, the Times Union and the Democrat and Chronicle, initially offered a combined reward of $2,500 for information leading to the arrest and conviction of her murderer, and all information each publication received was relayed to police. Numerous local businesses and residents added private donations to the reward fund, gradually leading the sum to exceed $6,000. Although police interrogated several suspects in the months following Colón's murder, all were cleared of involvement, and by December 21, the number of investigators assigned to the case on a full-time basis was decreased to three. In early 1972, five large billboards—each measuring 30-feet-by-12-feet—were erected alongside major Rochester expressways. Each bore an high picture of the child alongside the headline: Do You Know Who Killed Carmen Colón? Free use of these billboards was given for one month by the Rochester Outdoor Advertising Company.

Three classmates specifically observed her bracing the bag against a fence so that she could improve her grip as a brown vehicle drove past her.
