LOS ANGELES (AP) — Los Angeles authorities have announced murder charges for a man suspected of fatally stabbing a transgender woman whose body was found inside her burning home.

Police said at a news conference Tuesday that 29-year-old Kevyn Ramirez admitted stabbing Victoria Gutierrez in her house after a dispute and setting the fire earlier this month.

Lt. John Radtke said motivations for the killing are unclear and investigators are trying to determine if the killing may have been a hate crime.

Prosecutors said Ramirez and Gutierrez met online.

Ramirez is charged with murder during the commission of an attempted robbery and other counts.

Mariana Marroquin with the LA LGBT Center tells the Los Angeles Times that Gutierrez was active in the transgender community.
