Police in Vancouver, Wash., say Meshay Melendez, 27, and Layla Stewart, 7, were last seen alive on the morning of March 12. A friend alleged to police they last saw Melendez that day "unresponsive and naked from the waist down" in the car of her ex-boyfriend, Kirkland Warren. Warren was taken into custody on charges of tampering with a witness, violation of domestic violence orders, and unlawful possession of a firearm, in connection to the disappearance of the mother and daughter, a Vancouver police news release reads.

According to The Columbian, at the time of his arrest Sunday, Warren was out on bail after being charged with drive-by shooting, assault and felony harassment; he is accused of firing a gun at Melendez's apartment earlier this month. He has pleaded not guilty to those charges. On Wednesday, a person called 911 to report a sighting of what appeared to be two "life-sized mannequins" in a rural area in nearby Washougal, Wash., KPTV-TV reports, citing the Clark County Sheriff's Office. A preliminary investigation verified the mannequins were in fact the bodies of a woman and a young girl. Genetic markings lead police to believe they are the remains of Melendez and Layla, according to KATU-TV. An autopsy has been scheduled to determine their causes of death.
