A Baltimore man is a free after he was wrongfully convicted of first degree murder.

Lamar Johnson spent 13 years in prison before his charges were dropped Friday. Authorities had previously claimed that he had shot a man to death in broad daylight.

Johnson always denied that he had any involvement in the incident.

The Mid-Atlantic Innocence Project eventually helped Johnson with his case, as did David Benowitz, an attorney with Price Benowitz LLP, who worked pro-bono.

"It became very clear to me, very early on, that he was totally innocent," Benowitz said.

New witnesses ultimately came forward in the case, all of whom claimed Johnson had nothing to do with the murder.

He told WUSA9 the last 13 years have been at times frustrating.

"I used to tell myself, 'Lamar you're innocent. The truth will come to light and you will be exonerated'," he said.

Johnson always had the support of his mother, Kathy Taylor.

"I have always kept the faith because I believe in him," he said.

As for the future, Johnson says he plans to go to college and get a degree in business.
