KING COUNTY, Wash. -- The 15-year-old Burien girl accused in the stabbing death of 49-year-old Francisco Noe Pena has been charged with second-degree murder.

Prosecutors have also requested a decline hearing in order to try the teen as an adult in the April 4 death of Pena.

Deputies had an encounter with the suspect before learning about Pena's death. Around 12:30 a.m. on the night of Pena's death, his neighbor called 911 to report a very drunk teenage girl had broken a window and was pounding on the door.

Police arrived to find the teen intoxicated and belligerent, bleeding from the wrist. The girl was taken to hospital and released to her mother the next morning. No incident at the Pena residence was mentioned, but police did note that she had $150 in her purse.

Four days later, the victim's body was discovered in his home in the 11800 block of SE 203rd Street after a co-worker called deputies say Pena hadn't shown up for work for three days.

Deputies found the man in his garage, with a single fatal stab wound to his chest. Investigators said the garage door was open, but his body had been concealed by a garbage can and a lawn mower.

The murder weapon, a knife, was found near the body. His wallet, however, was gone and items were scattered around his body as if someone had gone through his pockets, according to the statement of probable cause.

A fingerprint was found on the knife which led detectives to the suspect. A shoe print, cell phone battery and Newport cigarette butts, which are all believed to belong to the suspect, were also found on the property. The suspect was known to smoke Newports and the victim did not smoke cigarettes, according to documents.

Detectives went to her home on April 6 and arrested her as she was leaving her apartment.

After her arrest, the girl was interviewed by detectives. She told them several different versions of events but eventually told them she had a prearranged prostitution date with Pena on Friday, April 4. She told detectives she was to be paid $120 for sex, according to court records filed in the case.

Pena had recently begun frequenting prostitutes following his divorce, a friend told investigators.

The victim picked up bottles of Crown Royal whiskey and vodka, then picked up the girl at a QFC in Burien around 8 p.m., investigators said.

The suspect then went to Pena's house with him and started drinking whiskey with him, she told detectives. She then changed her mind about having sex and called friends to come get her. She and Pena argued and went into the garage, according to court documents.

The girl said Pena grabbed her by the hair in the garage, forcing her to punch him. But Pena was not bleeding when she left, she said.

When investigators told her there was blood found inside the house, the suspect conceded that she "might have grabbed something" which, she later admitted, was a knife from a shelf in the garage.

The suspect said she "might have struck him" during the scuffle because she though Pena had something "sharp" or "shiny" in his hand. No other knives were found at the scene of the crime, investigators said.

She told detectives she later returned and went through the victim's pockets to remove evidence, but denied taking any money. She said she also took his laptop, fearing the police would find her information on it.

Deputies said the girl has had many previous contacts with police, including an arrest for prostitution. Her criminal record includes nine prior convictions, including four assault convictions.

According to police records, the girl has a sporadic attendance record at Tyee High School in SeaTac.
