ALBUQUERQUE, N.M. – Charges were imminent against a man suspected of killing his ex-wife and three others in New Mexico in a series of slayings that include the beating death of a New Jersey resident he claimed sexually abused him as a child, authorities said Monday.
Investigators over the weekend searched a house where Sean Lannon, his ex-wife and their children were believed to have lived in the city of Grants, about 80 miles (130 kilometers) west of Albuquerque. Police Lt. David Chavez would not specify what investigators were looking for, only that the warrants were for anything of “evidentiary value” as local and federal authorities try to piece together what happened.
“It’s a complicated case,” Chavez said. “It wasn’t just one event, so we’re having to look at many things.”
Authorities also were still looking into Lannon’s claims that he killed 11 other people in New Mexico. Chavez reiterated Monday that while anything is possible, it was not probable given that there were no records of people missing from the area or other police reports that would indicate there are potential victims.
Authorities said in court documents that Lannon, 47, admitted to the additional killings in a phone call to a relative, who told investigators he expressed remorse.
The case began March 5, when the bodies of Lannon’s ex-wife and three other people were found in a vehicle in a parking garage at Albuquerque International Sunport, New Mexico’s largest airport. They were identified as Jennifer Lannon, 39; Matthew Miller, 21; Jesten Mata, 40; and Randal Apostalon, 60.
It’s not clear how or when they were killed.
Chavez said the first indication something was wrong was when Miller's girlfriend reported him missing in late January. When detectives talked to his friends and associates in Grants, they learned the others might also be missing.
