Boston Marathon runne Jeff Bauman Jr. originally gained recognition after a photo of his extensive injuries was wildly circulated Monday. The 27-year-old recently revealed that he was not only a victim in the terrorizing incident but also a key witness.

The brother of the victim, Chris Bauman, announced Friday that moments before the blast that damaged both of Bauman’s legs, leading to amputations, Bauman said he saw one of the now infamous bombers, reported the Telegraph Friday.

“He woke up under so much drugs, asked for a paper and pen and wrote, ‘bag, saw the guy, looked right at me,” Chris said.

After Jeff's confession, he was soon after interviewed by FBI officials, giving agents a description of the man. The information was what allegedly helped the FBI track down the suspects, which led to the deadly shoot-out near Massachusetts Institute of Techonology Thursday night.

Bloomberg reported that the key witness told investigators that he saw a man wearing a cap, sunglasses, a black jacket and hooded sweatshirt look him in the eye before dropping a bag at his feet only to explode 2.5 minutes later.

The runner was first indentified after a graphic photo of him being wheeled away from the bombing site, his legs visibly gone from the shins down, hit the Web. Jeff's savior, cowboy hat-wearing peace activist Carlos Arrendondo, also received recognition.

Following the Monday attack, Jeff's father, Jeff Bauman Sr., wrote a note of thanks for the words of encouragement for his injured son on Facebook.

“Unfortunately, my son was just in the wrong place at the wrong time,” Bauman Sr. said. "Thank you for all your thoughts and prayers; they did help greatly."

According to Bauman Sr., the 27-year-old runner suffered from excessive vascular and bone damage following the attack. He was treated at Boston Medical Center.

According to multiple reports, suspect Dzhokar Tsarnaev, 19, is still at large.
