A woman identified as the wife of a Texas man suspected of killing five of his neighbours has been arrested, US authorities say, for hindering the four-day manhunt for the man who is also in custody. Divimara Lamar Nava, 53, identified as the wife of suspect Francisco Oropeza, was in custody in connection with the Friday night shooting, according to Montgomery County Sheriff Rand Henderson. Although Henderson identified Nava as Oropeza's wife, jail records list her as not being legally married. The two share a home address, according to the records. Nava had previously denied knowledge of Oropeza's whereabouts, Henderson said, but authorities believe she hid him in the home near Conroe where he was arrested on Tuesday. Lamar Nava was arrested early on Wednesday and was being held in the Montgomery County jail on a felony charge of hindering the apprehension or prosecution of a known felon, according to online jail records. The records do not list a bond for her and indicate she was arrested by state police at a home in Conroe. A four-day manhunt for Oropeza ended on Tuesday when authorities, acting on a tip, said they found the suspect hiding underneath a pile of laundry in the closet of a house. At a news conference on Wednesday morning in Coldspring, chief deputy Tim Kean said authorities spotted Oropeza, 38, on Monday afternoon in Montgomery County, prompting the lockdown of several schools. "We did confirm that was him on foot, running but we lost track of him. That was not a false alarm. That was him," Kean said outside the county jail. The Montgomery County Sheriff's Office had previously said reports of a possible sighting of Oropeza in the area was a false alarm. Kean declined to comment on the tip the led authorities to the home where Oropeza was arrested as well as on when he had arrived or how he got to there. Kean said the home had not been previously checked by authorities. Kean said there have been several other arrests "but I can't go into the details on that". Kean said Oropeza only mildly resisted arrest and was not injured. Kean said the home where Oropeza was arrested has a personal connection to the suspect. He declined to provide more details but said there was no indication Oropeza was about to leave. "I believe he thought he was in a safe spot," Kean said. Oropeza was expected to appear before a judge inside the San Jacinto County Jail on Wednesday and the judge would formally set his bond at $US5 million ($A7.5 million), Kean said. The home is near the community of Conroe, north of Houston and about 32km from his home in the rural town of Cleveland - where authorities say he went next door and shot his neighbours with an AR-style rifle shortly before midnight on Friday. Oropeza had been shooting rounds on his property and attacked his neighbours after they asked him to go farther away because the gunfire was keeping a baby awake, according to police.
