TUCSON, Ariz. (AP) — A pickup truck slammed into a group of 10 bicyclists waiting at a red light in southern Arizona, killing two riders from two states and leading to the driver's arrest, authorities said.

Three other bicyclists were injured in the crash Thursday afternoon in Tucson, including one critically, the Pima County sheriff's office said. The others had minor injuries.

The cyclists were waiting in a bike lane when Brian Lynch, 28, of Tucson, barreled into them, the sheriff's office said.

He was arrested on suspicion of driving under the influence and faces various manslaughter and aggravated assault charges. Sheriff's Deputy Ryan Inglett said he didn't know if Lynch had a lawyer yet.

Clare Rhoades, 72, of Santa Fe, New Mexico, died at the scene, and Kenneth Vieira, 68, of Tucson, died at a hospital, officials said.

Rhoades was a leader of Santa Fe Seniors on Bikes, a group of cyclists that ride and travel together, said her husband, Richard Hughes. The group met up with Tucson riders to explore part of the city and planned on visiting Saguaro National Park the next day, he said.

Rhoades was a talented artist and retired nurse practitioner who loved the outdoors, Hughes said. She kept busy cycling, hiking and boating and was also an expert skier.

"She was just full of energy and a real spark plug, and she lit up rooms when she entered," he said.

The truck that hit them belongs to Scott Roofing Co., which issued a statement late Thursday saying its prayers were with the victims' families.

"Scott Roofing Company joins with the entire Tucson community in mourning the loss of those who were killed and injured," the company said. "We are cooperating fully with law enforcement authorities as they continue to investigate today's tragedy."

The company did not immediately respond Friday to a message about Lynch's employment status.

Lynch was scheduled to make an initial court appearance Friday, Inglett said.
