(Portland, OR) -- A man is in police custody after allegedly holding a woman hostage and then killing her during a nearly ten-hour-long standoff at a home in Southeast Portland. The Portland Police Bureau says officers breached a barricaded door at the home and managed to arrest the suspect just after 1 o'clock this morning. Officers then found the woman dead inside the home. Police had responded to the home just after 3:30 yesterday afternoon after a woman called 911 crying, saying she was being held hostage. Police say the suspect opened fire on the officers several times during the standoff, forcing police to back off and set up a perimeter. Police eventually deployed a chemical agent into the residence, allowing them to gain entry.
