Two pedestrians struck by NY governor Andrew Cuomo's security detail in two days

(CBS/AP) ALBANY, N.Y. - For the second time in two days, a pedestrian has been struck and injured by an unmarked state police vehicle assigned to Gov. Andrew Cuomo's security detail near his home in Westchester County.

Cuomo spokesman Josh Vlasto said Friday that neither the governor nor any of his staff was in either vehicle during the accidents.

State police said 50-year-old Jeronimo Ardon Perez, of Mount Kisco, was hit in town on Route 117 at about 7 p.m. Thursday by a car driven by Investigator Gregory Panzarella. Perez was listed in serious condition Friday at a hospital.

The other pedestrian, 22-year-old Dolce Perez, was hit by a car driven by Sgt. Joseph Crispino at about 10:15 a.m. Wednesday on Route 133, also in Mount Kisco. She was taken to a hospital to have a head injury examined and was reported in fair condition Friday.

It wasn't clear Friday whether the two pedestrians were related.

Maj. Michael Kopy declined to comment on what caused the accidents, saying investigations were under way. He said both officers were on duty although neither was responding to an emergency.

Cuomo lives with his girlfriend, Food Network star Sandra Lee, and his daughters in a home off Route 133 in nearby New Castle.
