The bizarre way the young couple's relatives found out about their missing loved ones' escapades capped off a five-day bender that included four stolen cars, one attempted carjacking and two police chases in two states, police and prosecutors said.
Why Sykes and Bills allegedly embarked on their crime spree still wasn't clear Wednesday, but more details emerged about the couple, including that they have a history of heroin use, authorities said. Their 7-month-old daughter, Zoey, is now in the care of Bills' parents.
Sykes, 23, has been arrested at least three times for driving under the influence of intoxicants and driving on a suspended license, court records show.
On Aug. 17, Bills was arrested for burglary and related offenses after allegedly breaking into his neighbor's house in Lehigh County and stealing a computer and jewelry.
According to police, Bills, who lists himself as "independently wealthy" on Facebook, said he committed the theft because "times are tough."
Bills showed up for a pretrial hearing in his burglary case last Thursday, court records show.
The following day, he and Sykes - who live with Sykes' grandmother, Sharon Sykes, in the Allentown suburb of Macungie - asked to borrow her 2003 Mazda Protege to head to an appointment with Bills' attorney, Harry said.
She gave them permission, but they never returned, police said. It wasn't until Monday that Sharon Sykes reported the pair missing and her car stolen to Macungie police.
The next known sighting of the pair may have been on Sunday, when a Camden police officer tried to stop a couple in a Mazda Protege who he believed were buying drugs, said Jason Laughlin, a spokesman for the Camden County Prosecutor's Office.
That couple fled the stop and went on to Interstate 676, where they were able to lose police. Bills and Sykes have not been charged in that incident, but they are being investigated as suspects, Laughlin said.
The two-person crime wave allegedly continued Monday about 1 p.m., when Sykes and Bills stole the car of a delivery driver who had left his 2005 Nissan Altima unattended on Hancock Street near Laurel, in Northern Liberties, while he made a delivery, police said.
Sometime between then and Tuesday morning, the couple allegedly took the delivery driver's stolen car to Camden and ditched it when it broke down.
They then tried to break into an occupied car in Camden, but after finding the doors locked, they gave up and targeted the police cruiser of Camden Officer Sekou Reid-Bey, who had left his car unattended while conducting a traffic stop, Laughlin said.
Bills and Sykes jumped into the cruiser, hitting Reid-Bey as they sped away, police said.
That's about when the news helicopters started following overhead, watching as the couple led police on a high-speed chase around Camden, Pennsauken and then over the Ben Franklin Bridge into Philadelphia, where police stopped them. As Bills was being arrested, police said, Sykes jumped into the driver's seat of an unattended Philadelphia police cruiser and led city police on yet another chase through Fishtown and Northern Liberties before she was apprehended.
Both suspects were charged with driving under the influence, but police declined to identify the narcotics the couple used pending toxicology results.
Laughlin said they have been known to use heroin.
Meanwhile, Sykes' grandmother's car was found about 7:30 p.m. Tuesday on 17th Street near Packer Avenue in South Philadelphia, across town from where the couple allegedly stole the deliveryman's car.
Macungie Police Chief Harry said his department probably won't charge the couple for the alleged theft of the grandmother's car because they're already going to face so many charges in Camden and Philadelphia, including attempted murder, carjacking, DUI, fleeing and eluding police, and joyriding.
"I'm sure they will be doing time until their daughter's college graduation," Harry said.
