UPDATE: About 11 a.m. Thursday, police arrived at the Windsor Township home of accused baby-kidnapper Ummad Rushdi to resume searching for the body of 7-month-old Hamza Ali.
After a day of searching a wooded area in Columbia, police and a cadaver dog failed to find the body of a missing 7-month-old baby who police said was kidnapped and is feared dead.
A Windsor Township man remains in custody, accused of committing that kidnapping. But his charges could be upgraded if the child's body is found.
Seven-month-old Hamza Ali is feared dead after he went missing from a home in Upper Darby Township, Delaware County, on Sunday morning, according to police there.
About 5:15 p.m. Wednesday, police said they finished searching an area not far from the intersection of Routes 30 and 441 in Columbia, Lancaster County.
"We're done for right now," Columbia Police Officer Troy Engle said.
Nothing was found during the search, he said, and investigators are following other leads.
Participating were 15 law-enforcement officers from Columbia Police, state police, the FBI, the U.S. Marshals Service and Upper Darby police, Engle said.
One cadaver dog was used during the search, he confirmed.
The suspect: Ummad Rushdi, 30, of 979 Castle Pond Drive, is charged with kidnapping, unlawful restraint, false imprisonment, interference with the custody of children and endangering the welfare of a child.
He was arraigned late Wednesday afternoon and taken to Delaware County Prison on $750,000 bail, according to the office of Upper Darby District Judge Harry Karapalides.
A preliminary hearing has been tentatively set for 8:30 a.m. Aug. 19, court records state.
According to charging documents, Upper Darby officers were called to a home in the 6600 block of Chestnut Street Tuesday night and spoke to 20-year-old Zainab Gaal, Hamza's mother.
Rushdi, Gaal and Hamza are from York County and had been at the home visiting Rushdi's parents, according to police.
Mother afraid: Gaal told officers that when she awoke Sunday, her baby and Rushdi were missing, but both had been at the home Saturday night, documents state.
Gaal said she didn't give Rushdi permission to take Hamza and fears for her baby's life, according to charging documents.
The mother did not immediately call police because Rushdi's brother had been telling her the baby was fine, according to Upper Darby Township Police Superintendent Michael Chitwood.
Upper Darby police obtained a warrant for Rushdi's arrest Tuesday night.
Found at home: York Area Regional police officers arrested Rushdi at his home without incident overnight Tuesday and turned him over to Upper Darby police, according to York Area Regional Sgt. Jeff Dunbar.
A vehicle Rushdi was driving was found abandoned along Route 30 in Columbia, police said. Investigators believe Hamza was buried in that area, Chitwood said at a press conference Wednesday.
Rushdi's vehicle was seized so police could search it, according to Chitwood, who said that's the vehicle police believe was used to transport the baby's body.
"We believe that the child was killed inside (an Upper Darby home), probably early Sunday morning and driven to an unknown area up in ... the York/Columbia area," he said.
Phone messages left for Upper Darby Township Police on Wednesday afternoon were not returned.
