Investigators again turn to security cameras to help solve a crime.

Security cameras are everywhere, so increasingly, it seems, law enforcement is using the images they capture to help them investigate crimes.

On Monday, the Manatee County Sheriff's Office released images taken during a robbery at a 7-Eleven store in Bradenton.

And on Tuesday, the Sarasota Police Department released almost a dozen images taken by a camera at the Smoking Joe's bar, one of the last spot two British tourists are believe to have visited before they were shot to death in the Newtown neighborhood early Saturday.

In the latter case, detectives say the images don't necessarily show the killer or killers, but witnesses who might be able to fill in the blanks on the victims' activities in the hours before they were slain.

"The individuals seen with the victims ... are not suspects," a police news release states. "We would like to contact these individuals so that we can learn more details about the victims activities, and other people that may have contacted the victims.

So if you were at Smoking Joe's on Friday night/Saturday morning, see yourself in the pictures or have any information that might help police solve the crime, call Sarasota police Detective Johnathan Todd at (941) 954-7091.
