Jason Mihalko recalls April 15, 2013 - and his decision to call every one of his patients:

I felt that had I not contacted my patients, I would have engaged in a human error that I could not recover from. I would have been neglectful of my patients and would have violated everything that I believe in about the therapeutic enterprise.

Dic Donahue, critically wounded in Watertown in April, 2013, announced his retirement from the Transit Police Department today:

Following my injury, I committed myself to returning to active service in the department. It took nearly two years to accomplish that goal, fighting through pain and limitations, but I had a lot of help from some amazing doctors, my family, and my fellow officers. I did not want it to be taken from me without a fight. Unfortunately, I must now acknowledge the extent of my injuries and limitations. Physically, I cannot perform at 100 percent and must do what is right for myself, my co-workers, and my department. Therefore, I will step away from the job that I love so much.
