A Dartmouth man accused of stabbing his girlfriend to death last year has pleaded guilty to second-degree murder.

Tyler Dow Baglini, 31, admitted in Fall River Superior Court on Tuesday that he killed 31-year-old Kerri Fidalgo of Dartmouth.

Baglini entered St. Luke’s Hospital in New Bedford just before 5 p.m. on Sept. 20, 2024, with a large, blood-stained kitchen knife, claiming his girlfriend had been stabbed by a serial killer at her Atlantic Street apartment.

Police said they observed dried blood on his face.
