SAN YSIDRO (CNS) - A 6-month-old girl is safe today after her her 28- year-old father, who allegedly kidnapped her, was taken into custody a the end  of a SWAT standoff at a San Ysidro mobile home park, authorities said.

Joshua Ivan Martinez allegedly kidnapped Nayeli Martinez following a  domestic violence incident in Santa Barbara about 9 p.m. Sunday and drove off  with her in a black 2013 Ford Focus four-door with temporary dealer license  plates, authorities said.

Investigators initially thought the suspect was en route to Mexico and  might  have been in San Diego County, according to a Santa Barbara police  statement.

Police located Martinez by ``pinging'' his cellphone phone and  determined he was in the San Diego area, authorities said.

U.S. Justice Department investigators located the suspect's vehicle in  the 3800 block of Sipes Lane and requested assistance from the San Diego Police  Department around 5:45 p.m. Monday, San Diego police Sgt. David E. Jennings  said.

Local SWAT team members and crisis negotiators were dispatched to the  mobile home park where Martinez, who was believed to be possibly armed, was  holed up, according to Jennings.

Martinez surrendered around 8:20 p.m. and, according to Jennings, was  taken into custody without incident on charges stemming from the alleged  kidnapping. Nayeli was rescued uninjured.
