Investigators are trying to determine what caused a head-on crash in Easton that killed both drivers Saturday night. Police identified them as Mario Licona, 58, of Bridgeport, and Florence Mahony, 87, of Redding.

It happened on Route 58, just south of Center Road—an area that’s rural and scenic without many homes. Police said it can also be dangerous.

“We do have accidents on this road semi-frequently because of the nature of the road. It's an older, windy dark road. There are no streetlamps, and we have a lot of animal crossings here,” Capt. Jon Arnold said.

What led to the deadly crash over the weekend is still a mystery.

Police were called to the scene around 7:40 p.m. after several 911 calls about a head-on collision. A van traveling north and a car heading had slammed into each other, according to Arnold.

“One of those vehicles crossed over the center line, striking the other vehicle. At this time, we're trying to figure out who crossed over and why they crossed over," Arnold explained. "Did they have a medical emergency? Was there some impairment? Was there some problem with a vehicle? Animal in the road?”

It was also lightly raining, a little foggy, and dark at that time, Arnold said, adding that investigators don’t know if those factors played a role.

Arriving officers found both drivers trapped and alone in their vehicles. The van, driven by Licona, had rolled over and was on fire, Arnold said.

“Our officers tried multiple heroic attempts to remove that occupant from the vehicle, but due to the intensity of the fire, we were unable to activate that rescue,” Arnold told News 12.

Licona was pronounced dead at the scene, police said. Mahony, who was driving the car, had to be extricated and went to the hospital, where she later died. Arnold said the Fairfield Police Crash Investigation Unit was called out to the scene to help, which is typical in crashes of this nature.

On Monday, the area was still littered with broken auto glass and parts from both vehicles. There were also no noticeable skid marks which suggests the crash happened quickly. Arnold said the average speed on that stretch is 45-50 mph.

“What's also concerning in this area is the cell service is tough. So, any witnesses we had call in on 911, the calls were broken up. We didn't get a lot of information other than there was an accident at this location,” Arnold explained.

Police want to hear from anyone who saw something or whose security camera caught the van or car before the crash. Arnold told News 12 police are also hoping the vehicles’ on-board computers provide some answers.

“These families are forever broken now. We're going to try to figure out what occurred, so we can hopefully prevent it in the future,” said Arnold.
