Lawson and three other men were found dead inside city manholes near Coveleski Stadium last week.
The deaths of Lawson, 53, Michael S. Nolen Jr., 40, Jason Coates, 29, and Brian G. Talboom, 51, have all been ruled homicides.
Authorities released no new information Friday regarding the deaths of the homeless men.
[Jerry] Eason spoke fondly about Lawson at the Mass held at Our Lady of the Road, a drop-in center at 744 S. Main St. About 80 people — primarily friends and a few family members — attended the Mass, which was followed by a potluck dinner.
The Mass was for Lawson, a Catholic who stayed at the Catholic Worker House, but all of the victims were prayed for.
When the third and fourth bodies were found is when I began to worry about my family; specifically, I worried that Jessica would hyperbolically conclude—as she usually does—that we were all going to die at the hands of some homeless serial killer lurking in the sewers bopping people over the head; that he would find his way into the building through the drain in the laundry room. I decided not to tell her because as I parked the car at the curb outside Mello Place, just below the green awning, I happened to look up and see the train underpass in the distance and realize that it was the very place that the men were found.
