Mexico City , Mexico ( CNN ) -- An American jailer was the target in the shooting deaths of three people with ties to the U.S. Consulate in Ciudad Juarez , Mexican officials said . The jailer , Arthur Redelfs , and his wife , Lesley Ann Enriquez , were killed in a drive-by shooting in Juarez earlier this month . Enriquez was an employee of the U.S. Consulate in that city . Jorge Alberto Salcido Ceniceros , 37 , the husband of a Mexican employee of the consulate , was also killed at around the same time as Redelfs and Enriquez . A suspect arrested in the case gave new details on the high-profile killings , Mexican federal authorities said in a statement late Tuesday . Ricardo Valles de la Rosa , a member of the Aztecas gang , was arrested Friday based on military intelligence , the statement said . According to federal officials , de la Rosa told interrogators that he was a lookout for the operation that killed the two Americans . He said he got to know many leaders of the Aztecas , a street gang affiliated with the Juarez cartel , while imprisoned in El Paso County , Texas . Although he was born in Juarez , de la Rosa lived in El Paso for 30 years . One of the Azteca leaders called and ordered him to find where consulate employees were having a children 's party and to follow the white sport utility vehicle belonging to Redelfs , a jail guard in El Paso , authorities said . The call came days in advance of the killings , the statement said . De la Rosa followed Redelfs ' vehicle down a Juarez avenue , until being told to fall back because the shooters had the vehicle in their sights , the statement said . A few moments later , de la Rosa heard shooting . According to federal authorities , de la Rosa drove by the scene and saw that in addition to Redelfs , his wife , who was four months pregnant , was also dead . An infant in the back seat was uninjured . De la Rosa also admitted to involvement in four other homicides involving members or rival gangs , authorities said . No additional arrests have been made in the case . De la Rosa remains imprisoned pending the outcome of the investigation . Ceniceros ' wife was not traveling with him , but two of their children in the car were wounded . His white SUV looked very similar to the one Redelfs drove .
