? Baltimore County police say a Garden City father killed his wife and two daughters before killing himself in a Maryland hotel room.

Investigators say real estate attorney William Parente killed his wife, Betty, and 11-year-old daughter, Catherine, first. They died of asphyxiation and blunt force trauma Sunday, according to medical officials. Police say the older Parente daughter, 19-year-old Stephanie, was killed later Sunday afternoon by her father. William Parente then took his own life by cutting himself, according to investigators.

The family was found dead in a guest room on the 10th floor at the Sheraton Baltimore North Hotel in Towson. William Parente was found in the bathroom and the three others were found on the bed, according to police. Staff at the hotel found them after they did not check out as scheduled.

According to police, Stephanie Parente was a student at Loyola College in nearby Baltimore. Police say the family occasionally visited her and they believe that was the reason for the family's trip over the weekend. They have no motive in the killings.

Newsday reports the state attorney general had recently received a complaint from Queens attorney Bruce Montague, who says he invested $450,000 with Parente and couldn't get his money back. The FBI has opened an investigation.

Meanwhile, the Garden City community is in mourning. Family and friends created a memorial outside the Parente home. Some students at Garden City High School dressed in blue Wednesday, Catherine?s favorite color, and grief counselors were on hand in the district.

?It's tragic and it's shocking,? says Garden City High School senior Laura Steinhardt. ?I never would have thought anything like that would ever happen to anyone here.?

Father Joseph Schlafer, of St. Joseph's Church, says he?s known the family for years and that the congregation is shocked by the events. Schlafer says the Parentes were devout Catholics and loved by their fellow congregants. He says no funeral arrangements have yet been made.
