A New Jersey man concealed the remains of his adult daughter for more than three years in his former house, at one point moving the body into a crawl space, where it was discovered this week by a cleaning crew, authorities said Thursday. Fifty-seven-year-old Dennis Adler made an initial appearance in state Superior Court in Monmouth County to face a charge of disturbing human remains. Adler didn't enter a plea and was held on $100,000 bail. Police were called to Adler's former home in Keansburg on Tuesday after a cleaning service discovered the remains. It could take a few weeks to receive the results of an autopsy to determine the cause her death. The county prosecutor's office said Kimberly Adler was likely 23 when she died. According to the arrest warrant, Adler is accused of "repeatedly moving, disturbing and concealing the remains of K.A. on diverse dates beginning on 8/10/2008." Prosecutors would not provide further details on the investigation. County property records describe Adler as an "unremarried widower" at the time that the property was sold in June 2008 and said his wife died in April 2007. The couple had bought the property, which includes several buildings, in 1989. John Sheehan, who is listed as the buyer of the property, did not immediately return a telephone message left on Thursday. Some residents of a rooming house in Keansburg listed on the warrant as Adler's last known address said they hadn't seen him in about a year. Neighbors on the street of modest one-story homes where Kimberly Adler's body was found didn't want to comment on the discovery or said they didn't know the house's former owner. A pile of debris lay in back of the house on Thursday, while out front, television news trucks were gathered.
