MILPITAS -- Surveillance video shows a 26-year-old transient with a baseball bat chasing a man through a Great Mall sporting goods store and then hitting him at least 11 times in the head, according to a Milpitas police report.

The police statement of facts provides new information on the shocking June 7 homicide inside the Sports Authority store, including that the two men walked into the store together just before the killing.

Nathaniel Manlangit, the suspect, told the first police officer to arrive at the store that 31-year-old Carlos Carloca, of San Jose, had threatened him with a knife.

But the police report does not indicate whether a knife was found, the nature of the relationship between the two men, or whether there had been a prior altercation between the two that might have led to the Carloca's death.

"As of right now, nothing other than what was in the statement of facts is being released," Milpitas police Sgt. Gene Smith said.

The report says police responded at 10:49 a.m. June 7 to a report of a fight at the store.

When Officer Kita Inthasack arrived just seconds later, he found Manlangit covered in blood.

"The witnesses saw the victim lying on the floor with Nathaniel Manlangit standing over him and swinging a baseball bat at the victim's head," the police report says.

The report says Manlangit then made the following spontaneous statement to the officer: "He used a knife on me."

Surveillance video shows the two men walking into the Sports Authority together, the report says.

"Nathaniel Manlangit and the victim were seen looking at items inside the store together. (Manlangit) and the victim separated and (Manlangit) was seen walking around the store with a baseball bat," the police report reads. "The video showed (Manlangit) chasing the victim and once the victim was on the ground (Manlangit) struck the victim at least 11 times in the head."

Manlangit did not have any visible injuries, according to police.

Lisa McCrary, of the a Santa Clara County District Attorney's Office, said Manlangit is being held without bail for the charge of murder with use of a deadly weapon, an enhanced charge that may add time to a potential sentence if he's convicted.

The June 7 slaying was the first homicide in Milpitas this year. The last homicide occurred during an early morning robbery on Sept. 8, 2012, at the 7-Eleven at 1496 N. Milpitas Blvd., in which a store clerk was shot and killed by three masked men. No arrests have been announced in that slaying.

Two homicides were reported in Milpitas in 2011. The suspects in both of those cases were apprehended.

The June 7 killing was the third at Great Mall since it opened in 1994.
