State Rep. Nick Collins won a landslide victory on Tuesday as he secured the First Suffolk senate seat in a special election. Collins earned 86.23 percent of votes cast across Dorchester, South Boston, Mattapan and Hyde Park.

The next highest vote total went to former state Rep. Althea Garrison with 8.66 percent, while 3.37 percent of voters cast ballots for Donald Osgood Sr. and 1.74 percent opted for write-in ballots.

The election was characterized by low voter turnout, with only 4.2 percent of the electorate casting votes across 77 precincts for a total of 4,713 votes tallied.

Senator-elect Collins will serve the remainder of the term of former state senator Linda Dorcena Forry, who vacated her seat in January. This term will run until the fall, at which point Collins intends to again run for the First Suffolk seat.

He will be sworn into office on May 9 by Governor Baker. There will be a ceremonial swearing-in at the senate on May 10.
