ABCNews.com(DETROIT) — Three women were killed and three police officers injured in a dangerous barricade incident at a Detroit home that lasted from Sunday night through Monday, Detroit police said.

The suspect, Lance Smith, 49, who police said has seven legal guns registered to his name, was heard saying, “I will not be taken without a fight,” Detroit Police Chief James Craig said at a news conference Monday morning.

The three injured police officers suffered non-life-threatening gunshot wounds to the leg, Craig said.

The “dangerous” standoff came to an end on Monday when police made entry into Smith’s home through robots and found the suspect dead inside, police said, adding that they believe he took his own life.

A woman who police said was Smith’s girlfriend was also found dead inside, Detroit Police Deputy Chief Elvin Barren said at a news conference.

The other two women were found shot outside the home, police said. Two of the victims were in their 50s and another was age 46, Elvin said.

There “easily could have been a higher death toll,” Barren said.

The barricade began Sunday night with a 911 call to police about shots fired from a home, Craig said.

The suspect fired “an unknown number of rounds, basically attacked first the civilian victims,” Craig said.

The suspect then allegedly fired at an off-duty officer who lives in the neighborhood and then fired at the responding Detroit police officers, Craig said.

The Detroit police officers “were pinned down by gunfire for at least an hour,” Craig said. “And during that hour time, they were waiting for the response of our special response team who did a phenomenal job quickly getting in and safely moving out those who were shot, including those who were shot fatally.”

An armored vehicle was brought in to help get those officers to safety, he said.

Then came a second attack on the officers, Craig said, during which the third officer was shot and then rescued by his partner.

The last time police heard from Smith was at about 2 a.m. When they attempted to speak with him through the loudspeaker, Smith would not say anything other than the threats he made threats he made early on, Barren said.

The standoff lasted 14 hours, Elvin said.

It is unclear if Smith had a phone, but he did not communicate with anyone during the standoff, Elvin said.

Multiple fires were also lit in the home, allegedly by the suspect, police said, noting there is no heat inside the house. Schools in the area were closed to keep children away from the ongoing incident.

Smith did not have a criminal history and did not have any diagnosis of mental illness, according to Elvin.
