The father of the Delaware man arrested outside a Westfield school Thursday, who police say had a handgun and more than 100 bullets, said his son may have traveled there to see a former or current girlfriend. He also said another of his sons called police Thursday about the brother.

Thomas J. Wilkie’s father, George, answered the door at the family’s home on a quiet residential street of single family homes in Bear, Delaware, on Friday afternoon.

Thomas has lived at the house since his divorce a few years ago, the father said.

“I have no idea exactly what went down because we have not been contacted by the police up there,” he said, referring to New Jersey authorities.

Westfield police arrested Wilkie, 46, at the Tamaques School at about 4 p.m. after getting a tip from New Castle County, Delaware, police, who were looking for him. He was holding a .45-caliber handgun loaded with hollow-point bullets, and had two more loaded magazines of ammunition in his possession, while 130 additional rounds were in the vehicle’s trunk, police said earlier Thursday.

George Wilkie doesn’t believe the incident is at all related to his divorce.

“The divorce was a couple of years back and everybody moved on,” he said.

“I’m not sure who he was going up to visit,” George said, though he has heard it could have been a girlfriend or ex-girlfriend.

NBC New York, citing a senior law enforcement source, reported Friday that Thomas Wilkie “targeted the school because of a relationship gone bad with a faculty member.”

NBC reported that Wilkie actually entered the school -- without a gun -- and called the woman, who was apparently not at the school at the time, but told him she would return. He then called his brother, who called police, NBC reported.

George confirmed that Thomas’ brother, Chad, contacted New Castle County, Delaware, police trying to find out where he was. That led to county police contacting Westfield police.

George said his son Thomas isn’t a gun enthusiast.

“I’m not even sure when he bought this gun that he’s alleged to have. It’s something that I’ve never seen.”

Thomas Wilkie is currently unemployed, but previously worked as a truck driver.

“He has some issues, some medical issues that we’ve been working with," George Wilkie said.

"This is kind of off the wall,” he said of his son’s arrest. “I don’t know what would drive it, but it is what it is. I just have to wait and see what they say is going to happen and when things are going to take place. We’re just going by what we hear on the news ourselves.”

George declined to comment further on his son and the arrest until he learns more from police.

“We’re hoping that he will have an opportunity to call here and we’ll get a chance to talk with him and see what’s going on," he said.
