Talk About a Dysfunctional Family

The O'Neills of Newtown Square are not your typical family.

Sean O'Neill, Jr. shot and killed his good friend during drunken gunplay in 2006. His sister Roisin O'Neill allegedly drove the wrong way on I-476 in a drunken mess and killed a grandmother on her way to visit her family.

And their father, Sean O'Neill, Sr., may be deported for lying about his former connections to the IRA.

If you thought your family was tragic, think again. Let's start with the son.

With his parents away for Labor Day weekend, O'Neill Jr., 17, threw a drinking party at his house. In a drunken stupor, O'Neill picked up his father's gun and began to play around with his buddy Scott Sheridan. The gun went off and Sheridan, 17, was killed.

Sean's sister Roisin called police after she found him clutching his friend's lifeless body in the driveway of the family's sprawling home.

O'Neill Jr. was found delinquent in juvenile court of shooting his friend and classmate at Cardinal O'Hara High School. His blood-alcohol level was 0.175 at the time, more than twice the adult legal limit, police said.

Now 19, he is due to be released this month from a second stint in a juvenile facility, where he was sent last fall for a probation violation in the involuntary manslaughter case.

On to Roisin – she is scheduled to stand trial Monday in a homicide case of her own. The 22-year-old eldest child was charged in the wrong-way, alleged drunken-driving crash that killed a Massachusetts grandmother.

Roisin had a 0.197 blood-alcohol level when she left a bar and drove the wrong way on Interstate 476 early on Sept. 12, traveling three miles before striking the car driven by Patricia Waggoner, 63, of Brimfield, Mass, according to police.

Waggoner was in the area to visit her grandchildren in Media.

Sean O'Neill Sr., a developer and longtime Irish pub owner, pleaded guilty Thursday to weapons, immigration and tax fraud charges.

O'Neill lied about his ties to an Irish Republican Army-linked youth group when he came to the United States in 1983, took part in a sham marriage to stay here and then married his wife Eileen without ever divorcing the first wife.

He also paid some employees off the books at Maggie O'Neill's Irish Pub in Drexel Hill from 1997 to 2006 and avoided paying taxes that investigators said cost the government between $80,000 to $200,000.

O'Neill owns a construction company, a restaurant, a bar and a property development business, a home in Newtown Square another property in Bucks County and a home down the shore in Sea Isle, N.J.

He faces a maximum sentence of 146 years in prison, three years supervised release, and a $4 million fine when he is sentenced in July. The question of whether he'll be deported still has to be decided in an immigration court.
