Wearing a baseball cap and hoodie, Mayra Velasquez walked up stairs to a second-floor Arlington apartment at 10:36 p.m. on Jan. 19, 2012, then knocked on the door, law enforcement authorities allege. After about a minute, Irasema Chavez let her in.<\/p>\n

There, in unit 416 in a building in the South Collins Street corridor, Velasquez stabbed Chavez about 100 times<\/a>, flinging blood on the white walls, authorities allege.<\/p>\n

Last week, Arlington police arrested Velasquez on suspicion of capital murder.<\/p>\n

The predicate crime that is the basis for the capital murder offense is not clear, nor is it publicly known what evidentiary development led to the cold-case arrest<\/a>, which occurred on Thursday. Police plan to answer questions on the case at a press conference with the FBI on Wednesday.<\/p>\n

The relationship between Velasquez and Chavez is also not clear. Chavez was 32. Velasquez, whose current home address is in Dallas, was then 27.<\/p>\n

A state district court judge denied Velasquez a bond, and she is being held in custody at the Tarrant County Jail.<\/a><\/p>\n

Velasquez\u2019s defense attorney, Vincent Carrizales, did not immediately return a reporter\u2019s telephone message.<\/p>\n

The Star-Telegram featured the case in a 2018 episode of the Out of the Cold podcast<\/a>.<\/p>\n

A test of a single drop of fresh blood left behind on a nightstand in Chavez\u2019s bedroom revealed that it belonged to a woman, though not Chavez nor a woman she had been dating and with whom she had broken up that night, police have said. Friends of Chavez told detectives that the girlfriend may have been selling drugs at Dallas nightclubs and that perhaps Chavez was indirectly involved.<\/p>\n

In 2016, Arlington police paid a Virginia-based company to use an analysis of the nightstand blood drop DNA to predict the suspect\u2019s physical appearance.<\/p>\n

From those genetic predictions, the company created a composite image. It resembles Velasquez.<\/p>\n

DNA tests ruled out Chavez\u2019s girlfriend as the stabbing suspect, police have said.<\/p>\n

Only a large flat-screen television appeared to be missing from Chavez\u2019s apartment. Police surmised the killer may have known that Chavez had surveillance cameras so that she could keep watch over her pickup truck and that the recordings from those cameras could be watched on that television. But the killer left behind the recording device, and police recovered video of the suspect walking up the stairs.<\/p>\n
