The bodies of two men who had been bound with duct tape and stabbed numerous times were found in the Schuylkill River in Philadelphia early Wednesday morning.
The bodies were located after police came upon a third man walking along the road who told them he managed to get out of the river after also being bound and stabbed.
This man, 20 years-old, was not weighted down and was able to swim to shore. He was last reported to be in stable condition.
Police say the other two men's throats had been slit and that they had been tortured.
Police said they do not yet know the identities of the two dead men, but they believe that the killings were drug related. They're also looking into a possible gang connection.
Investigators said at least one was weighed down with a makeshift anchor. A roofing cement bucket was seen pulled from the water during the recovery.
Police said the man walking along the road said he was alone when he was abducted, blindfolded, thrown in a van and robbed.
