San Francisco ? The parents of a 17-year-old boy killed by an escaped tiger at the San Francisco Zoo reached a settlement in their wrongful death lawsuit, their lawyer announced Friday.

Attorney Michael Cardoza said the family of Carlos Sousa Jr. has asked that the amount of the settlement remain confidential. He said the zoo agreed to erect and maintain a bench in memory of the San Jose teen as part of the settlement.

Cardoza said the San Francisco Zoological Society’s insurance carrier would pay the entire settlement and no public funds would be used.

Sousa was mauled to death on Christmas Day 2007 when a Siberian tiger escaped its enclosure and attacked Sousa and two of his friends.
