LYNN – Josh Rockwood never heard of Donald DiTullio, but the Lynn resident has something in common with the Sept. 11, 2001 terror attack victim memorialized with a sign at the corner of Lynnfield and Dartmouth streets.Rockwood graduated from Lynn Vocational Technical Institute this year. DiTullio graduated from Tech?s predecessor – the old Lynn Trade School – in 1970, according to his sister, Janice Fleming.DiTullio and his girlfriend, Janis Lasden, were aboard American Airlines Flight 11 when terrorists flew the airliner into the World Trade Center?s North Tower in New York City at 8:46 a.m., 11 years ago today. He would have turned 60 this year.Rockwood was a second-grader the day the attacks occurred.?I remember the teacher ran in hysterical. When I got home, my parents told me about it. They were upset,” he said.Recounting the timeline of 9/11The memorial sign erected in DiTullio?s memory is located a few blocks away from Judge Road where DiTullio grew up with older sisters, Joanna Cook and Janice Fleming.?We moved there in 1956. He was a Lynn boy, born and raised,” Fleming said on Monday.Fleming is happy her brother?s name marks the edge of his old neighborhood, but she doubts many people who drive past the sign know why it is there. Union Hospital employee Stephen Trzcinski knows and he thinks about DiTullio and Lasden when he drives by the sign on his way to work.?Eleven years ago and it?s still a terrible memory,” he said.Richard Gallant of Lynn never heard of DiTullio even though he also drives by the sign almost every day. On Monday, he recalled how his wife woke him from a nap 11 years ago to tell him about the attacks.?It stunned me – to have it happen on our own turf,” he said.Fleming and her sister and their mother, Marjorie DiTullio, donate a $500 scholarship annually to Tech graduates in their brother?s and son?s memory. They will spend today, Fleming said, in sad remembrance.?The day creeps up on you and then it?s here,” she said.The events of 11 years ago left Fleming with memories and also a reminder to “remain vigilant and know your surroundings.” Rockwood said one of the pivotal events of his childhood should serve as an inspiration for young people to visit the graves and memorials of those who lost their lives that day.?I don?t think we do enough,” he said.Thor Jourgensen can be reached at [email protected] Memorial Events in Greater Lynn Area ?
