Martinez sentenced to life in prison


Prosecutor James Gubitose, in his opening statement, said Martinez hit Walker with a shotgun blast so powerful it sliced through the side of his skull. After the killing, Martinez went onto to live a double life. In Lowell, he was a football player who went to college. His weekend activities in Lawrence he kept hidden from his girlfriend, Gubitose said.

Martinez was defended by Boston attorney James McCall, who argued police lacked fingerprints, DNA, fibers and a weapon to tie his client to the crime.

After his death, Walker’s picture was used on an anti-violence billboard over South Broadway in Lawrence. Murray said she hopes she can be a resource and provide support to other mothers who lose their children to violence.

Gubitose and fellow prosecutor Kim Faitella praised the work of lead investigators, State Trooper Anthony Schena, and Lawrence Police Detective Barry Desjardins.

District Attorney Jonathan Blodgett, in a statement, described the case as a “cold blooded brazen murder.” He lauded the bravery of a witness who came forward after seeing the surveillance video, which led to Martinez’s arrest.
