NEW YORK CITY ? The parents of an Alabama teen who disappeared last May in Aruba filed a wrongful death lawsuit Thursday against a Dutch youth questioned in the case.

The lawsuit, filed in Manhattan court, seeks unspecified money damages against Joran van der Sloot, 18, and his father. Both were served with a summons while in New York, a lawyer for the missing teen’s family said.

Natalee Holloway, 18, was last seen May 30 leaving a bar with van der Sloot and two other residents of the Dutch Island. Her body has not been found and no one has been charged.

The lawsuit was filed by Elizabeth Ann Twitty, of Alabama, and Dave Edward Holloway, of Mississippi, the missing teen’s mother and father.

Van der Sloot and Surinamese brothers Deepak Kalpoe, 21, and Satish Kalpoe, 18, were arrested June 9 on suspicion of involvement in Holloway’s disappearance. Van der Sloot admitted he was with the teen but denied any wrongdoing. All were released.
