Police in two suburban municipalities and the Montgomery County District Attorney's Office are continuing investigations into separate traffic incidents involving two of Eagles coach Andy Reid's sons.

The first incident, on Tuesday morning, involved Britt Reid, a second man, and a gun. Law enforcement officials would not say who possessed the weapon.

NBC10, quoting a law enforcement source, reported last night that investigators found a gun in Britt Reid's car, and a platinum handgun during a search of the Reid home Tuesday night in Villanova. That gun was reportedly in a lockbox in the basement.

When asked last night if a search warrant had been served on the Reid home, Montgomery County First Assistant District Attorney Risa Vetri Ferman said: "West Conshohocken police served two search warrants yesterday. . . . I will not comment on what was found during the course of the search."

In the second traffic incident, police said they found Garrett Reid in possession of drug paraphernalia after he was involved in an automobile accident Tuesday afternoon.

The Reids and the Eagles declined to discuss the incidents.

"The Reid family does not have any comment at this point," Derek Boyko, an Eagles team spokesman, said yesterday.

The incident involving Britt Reid, 21, was a confrontation with another man on Matson Ford Road in West Conshohocken. The second man has not been identified.

"There was a report of an incident where a gun was displayed," said Ferman. She would not say who handled the weapon.

Local police would say only that they were investigating an incident involving Britt Reid.

Later Tuesday, Garrett Reid, 23, drove his Jeep Liberty SUV through a red light at Germantown Pike and Arch Road in Plymouth Township and collided with a Ford Taurus, police said.

The other driver, a 55-year-old woman from Mount Carmel, Northumberland County, was flown to the Hospital of the University of Pennsylvania after the midafternoon accident.

She was treated late Tuesday night and released. Police have not identified her.

During the investigation, drug paraphernalia was found on Garrett Reid, according to Joseph Lawrence, deputy police chief for Plymouth Township. Speed was a factor in the accident, police said.

Garrett Reid, who was not injured in the accident, submitted to alcohol and drug testing. Results will be available in a few weeks.

According to official state electronic court records, in 2001, Garrett Reid pleaded guilty to three speeding charges, operating a vehicle without a valid inspection, and disregarding a traffic-control device in Radnor Township.

In April, Britt Reid pleaded guilty to speeding in Philadelphia and was fined $132.50.

Britt Reid is also a defendant in a lawsuit involving a Wynnewood man, Murray Nathanson, who says he was injured in a 2002 accident involving Reid.
