The home is owned by the Mount Zion AME Church, which sits next to it.
But both police and church officials say that while the house is church property, it's used as a rental home and not associated with church business.
Darby Borough Police Chief Joseph Gabe said his office is working with the Delaware County District Attorney's Office as well as other agencies in the search for Robinson.
A church official called it a tragedy and added the victim was not a member of the church.
If you have any information about Robinson's whereabouts, you are asked to contact police.
