"My client was just trying to swerve and avoid," Sigman said. "Brady was playing the game of chicken, in this case. He was coming direct to challenge my client on a bicycle, without a helmet, without reflective gear."
Assistant District Attorney Mark Levenberg said that Alleyne had an obligation to stop his car but chose not to.
"He drove his car in a reckless manner, he caused the death of another individual, and he could have avoided it," Levenberg argued.
Municipal Judge David Shuter said that he would let Alleyne's fate be decided at trial and held him on charges of homicide by vehicle and involuntary manslaughter. He is free on bail.
Sigman said that his client was remorseful despite the friction between him and Brady. He noted that Alleyne pulled over and called 9-1-1 after the crash and that police did not write him any tickets related to the crash.
"Our evidence is that Brady was stalking the mother of his children and my client for a period of time," Sigman said.
The collision on Musgrave Street near Meehan Avenue caused Brady to flip over the handle bars of his bike, hit the car's hood and land on the street, where Alleyne ran over him with one tire, causing crushing injuries, a police officer testified.
The car was traveling 10 to 15 mph in a 25 mph zone, the officer testified.
Betty Brady, 37, the victim's sister, left the courtroom in tears upon hearing the details of her brother's death.
"I'm just happy that the charges stuck, and I can not wait to proceed further with the case to seek justice for my brother, Officer Marc Brady," she said.
