Henderson, NV (KTNV) -- The 16-year-old teen suspected of killing his mother and brother the day after his birthday is described as anti-social in an affidavit of warrant issued by the Henderson Police Department.
The paperwork also said Adrian Navarro-Canales didn't have any friends in the area and that he was known to be "extremely volatile, defiant and violent" towards his mother Elvira Canales-Gomez. It also said that he was known to push or punch her.
It was also noted in the warrant that Adrian Navarro spent much of his time playing video games and was not currently enrolled in school.
Henderson police believe Canales-Gomez and her 9-year-old son Cesar Navarro were killed on Sept. 17 between the hours of approximately 3:30 and 5:30 p.m. based on the last time that Elvira was seen and had contact with her boyfriend.
It was her boyfriend, Carlos Rubio-Villanueva, who first became concerned about Elvira after not being able to reach her for a couple of days. He was the first to request a welfare check by Henderson Police Department.
Henderson Police Department visited Canales-Gomez's Sunridge Apartment a total of three times before finally making entry on Sept. 21. Entry was made on that date after being contacted Ana Martinez, who had also requested a previous check. Martinez was the niece of Canales-Gomez.
Upon entry, Henderson police located Cesar Navarro in a bathtub and his mother on the floor next to the tub.
During the investigation, police learned that Canales-Gomez had celebrated Adrian's birthday with her two sons and her boyfriend on Sept. 16.
The very last time that Rubio-Villanueva heard from Elvira was when she called him at 3:10 p.m. Sept. 17.
The first welfare check was made on Sept. 18. That was also the same day that Adrian's father Enrique Velasquez, who lives in California, received a text from his son saying he was sorry he had not texted earlier and that the others were fine and could not talk because they were asleep.
Another welfare check took place on Sept. 19 after Rubio-Villanueva visited the apartment again and was still unable to make contact. Henderson PD responded shortly before 4 p.m. but did not make entry into the residence.
The third welfare check happened shortly before 9:15 p.m. Sept. 19 at the request of Ana Martinez.
The final welfare check took place at about 11:16 a.m. Sept. 20, also at the request of Martinez.
Police have not been able to locate Adrian Navarro. The teenager had expressed desire previously to go back to Mexico but his identification documents were found in the apartment.
Anyone with information on Adrian's whereabouts is asked to call 911 immediately.
