Hilary Michalak, 27, of Largo, died Saturday morning from injuries sustained after a truck hit her and Robert Lemon as they rode a tandem bike around 6:15 a.m. Sept. 2, Rob Shaw, Clearwater Police spokesman, said in a release.
Lemon, 25, died the day of the accident at St. Joseph's Hospital in Tampa.
Christopher Patrick Weed, 29, blacked out after driving home from work at Shephard's on Clearwater Beach and doesn't remember anything until he awoke in the shower later Sept. 2 and saw the incident on the news.
Weed's 1997 Nissan pickup truck was found parked in his backyard without a windshield.
Weed was arrested the next day and charged with leaving the scene of an accident involving death and leaving the scene of an accident involving serious bodily injury.
"That second charge is likely to be upgraded because of Michalak's death, but it will be up to the Pasco-Pinellas State Attorney's Office to do that," Shaw said.
Weed remains in Pinellas County Jail.
