Thousands turned out to remember and honor the two officers.

On Friday, December 8, Wolff was involved in a minor crash and was pulled over on I-270. Cohen pulled over to help. Both men were out of their cars when another driver swerved to avoid traffic and hit the officers.

Wolff, 36, was an FBI Supervisory Special Agent with an 11-year tenure at the Federal Bureau of Investigation. Cohen, 33, was a nine-year veteran of the Office of the Maryland State Fire Marshal.

At Sander Cohen's funeral, Governor Larry Hogan said he died a hero helping someone in need.

"I'm here today as the Governor of Maryland representin all the people of a grateful state to honor the sacrifice of one of our true heroes. A man who dedicated his life t public service and who never hesitated to offer a helping hand, right up until his last breath on this earth," said the Governor.

Cohen was a Rockville native who started volunteering with the Rockville Fire Department when he was 16 years old. Over the past decade, he served with the state's fire marshal's office where he made good friends.

Friends recounted several stories highlighting Cohen's good nature and playful attitude. They say he was a jokester who always made them laugh.

Sander Cohen was also dedicated to job and very thorough.

State Fire Marshall Brian Geraci recalled meeting Cohen for the first time when he was visiting regional offices.

"As we went went around the table and got to Sander he pulled out a full page list of things that needed to be done. He had everything written own by subject matter," he said. "And I just looked at it and I said, 'well, here we go!'"

Geraci broke down as he told Cohen's family, that his memory will live on in the qualities he lived by...goodness, service and self-sacrifice.

"Please know that we will always be there for you in the days, weeks, months ahead as your extended family. I will miss his smile...and the 'hi boss, how's it going?' every time he'd come to my door," said Geraci.

Friends and family of FBI agent Carlos Wolff also gathered to remember the public servant.

Maryland State Police say the man who hit the officers had swerved to avoid hitting other cars in another lane.

No charges have been filed in the crash.
