TOPEKA, Kan. (AP) — Topeka police have identified a woman who was found dead inside an apartment after a 16-hour standoff with law enforcement officials.

Police spokeswoman Lt. Colleen Stuart said Monday the woman was 33-year-old Tiffany Montalvo, of Eudora.

She and 33-year-old Juan Lucio, of Topeka, died during the standoff. They were found dead Friday after police sent chemicals into the home.

Stuart says a preliminary investigation indicates the deaths were a murder-suicide.

Stuart said Monday it will take weeks to complete toxicology reports for Lucio and Montalvo.

No officers were injured during the incident.
