Police have narrowed their search for the suspects who killed two brothers -- slitting their throats before dumping their bodies in the Schuylkill River -- and critically injured another man over a $100,000 debt.
"We'll be coming to get you shortly," said Philadelphia Police. Capt. James Clark when asked if he had a message for the five people suspected in the abduction and double homicide.
Authorities learned of the barbaric crime Wednesday morning when the surviving victim, 23-year-old Thanh Voong, climbed from the banks of the Schuylkill River and began screaming for help around 4 a.m.
Hours earlier, the abductors were holding the three men -- who have ties to gangs and are well-known to authorities -- at a home on the 2400 block of 72nd Street, according to investigators.
The suspects were holding the brothers -- both in their late 20s and originally from Vietnam -- captive after they gambled away $100,000, which they were given to buy drugs, according to reports.
Voong showed up at the house with $40,000 to pay off the debt, but it was not enough to satisfy the suspects, sources said.
Early Wednesday morning, investigators found the bodies of the two brothers submerged in the water. Their throats were slit and both were bound with tape and tied to buckets.
Investigators removed similar buckets filled with roofing materials from the home on the 2400 block of 72nd Street Thursday.
Neighbors told NBC10 a woman and five children lived in the home. But they fled in an apparent rush since food was still on the stove when police arrived, according to reports.
Authorities also towed away an Audi A8 sedan Thursday as part of the investigation. They did not disclose how the vehicle,which was found on the 22nd Street overpass above the Vine Street Expressway, was related to the crime.
Police said they know who committed the crimes, but they are still searching for the suspects.
"They have obviously means, they have a lot of money, " Clark said. "They have a lot of different locations they've lived at through the years so right now we don't know where they're at or where they're headed."
As the investigation continues, Voong is recovering from seven stab wounds at Hahnemann University Hospital.
