In Monday’s running of the 116th Boston Marathon, 53 runners who identified themselves as Dorchester residents finished the trek as scorching temperatures greeted the 21, 554 who came from around the world to compete.

Murphy School teacher Chris Brum, 28, who finished in 4 hours and 42 minutes, ran the route with a team of ten, including three other public school employees, to raise money for the non-profit Technology for Autism Now. Brum aimed to raise at least $4,000 to help meet the group’s overall goal of $40,000. Funds will be applied to the development of mobile applications to support communication solutions for people with autism.

Brum has taught multi-handicapped students for the past few years at the Murphy K-8 School. In his own classroom, he says that he has seen severely handicapped children with various developmental disabilities respond well to iPad applications and other mobile devices because the apps encourage response via touch-screen ability, pictures, and sounds.

Technology for Autism Now was started by Marie Duggan, a parent of an autistic child in the public school system, to seek technological solutions for those with autism as well as for health professionals, caregivers and teachers.

The winners in the male and female categories were both Kenyan: Wesley Korir, 29, finished his first marathon in Boston in 2:12:40. Sharon Cherop, 28, topped the women in 2:31:50, a mere two seconds ahead of the second-place finisher.
