State Rep. Russell Holmes and Suffolk County Sheriff Steve Tompkins aren’t waiting to see who might run to replace Tim McCarthy as the city councillor from Hyde Park, Mattapan and Roslindale. Both have endorsed Ricardo Arroyo for the seat.

Arroyo, the son of former at-large Councillor Felix Arroyo and the brother of former at-large Councillor Felix Arroyo, is making his first bid for elected office in the fall elections. McCarthy announced his retirement from the seat at the end of this year.Tompkins, a Hyde Park resident, said Arroyo would be a champion of programs that will help people stay out of his jails and become productive members of society.

In addition to Arroyo, Yves Mary Jean of Roslindale says he intends to run for the seat.
