(CNN) -- A former hospital worker systematically shot and killed four people in upstate New York on Saturday, authorities in two counties said.

Former hospital worker Frank Garcia, 34, has been accused in the shooting rampage.

Frank Garcia, 34, was arrested Saturday afternoon. Garcia knew all four victims, police said, but they didn't reveal details about the relationships.

"The individuals who were shot were known to the suspect. It was not necessarily a random act," Monroe County Sheriff Patrick O'Flynn said.

The first two victims -- Mary Sillman, 23, and Randall Norman, 41 -- were fatally shot before 5 a.m. at Lakeside Memorial Hospital in Brockport, where Garcia was once employed, O'Flynn said. Another woman was wounded and is undergoing treatment at a nearby hospital, he said.

The second shooting happened at a house in nearby Ontario County on Saturday afternoon.

Christopher Glatz, 45, and his wife, Kim, 38, were killed "execution-style" while their two teenagers were in the suburban Rochester home, Ontario County Sheriff Philip Povero said.

The teens were not wounded, but it is unclear whether they witnessed the event.

Povero said neighbors reported Garcia went door-to-door looking for the Glatzes' home.

"He was in fact looking for the residence," Povero said. "He was saying different things to different people, but he was clearly looking for that home."

Ballistic evidence has connected the two crime scenes, Povero said. Investigators found the matching brass cartridges from a pistol found on Garcia when he was arrested, he said.

Garcia was arrested at a restaurant Saturday afternoon, CNN affiliate R-News in Rochester reported.
