Surveillance video  of George Zimmerman arriving at a Sanford, Fla. police station indicates what may be an injury to the back of his head, a Daily Caller analysis shows.
ABC News published the video Wednesday evening. Zimmerman is the man who shot and killed 17-year-old black teen Trayvon Martin a month ago.
“A police surveillance video taken the night that Trayvon Martin was shot dead shows no blood or bruises on George Zimmerman,” ABC News reporter Matt Gutman wrote , noting that Zimmerman told police “he shot Martin after he was punched in the nose, knocked down and had his head slammed into the ground.”
ABC News reported that Zimmerman appears uninjured in the video. But a still image from the video indicates what appears to be a vertical laceration or scar several inches long.
ABC did note that at the 49-second mark in the video, one of the police officers accompanying Zimmerman stops to look at the back of Zimmerman’s head for several seconds. Zimmerman, as ABC News noted, did not visit the emergency room after police interviewed him.
