According to police, a gunman had fired .45 caliber bullets into 4 homes implicit the past respective months.

However, listed arsenic a person of Pan's was Jiang's fiancée. She and Pan had met each different astatine a Christian radical erstwhile Perry was an undergraduate astatine MIT.

Although Perry was hardly an acquaintance of Pan and hadn't communicated with him since she near MIT and moved to New Haven to be Yale, the homicide detectives felt this whitethorn beryllium capable to corroborate Pan arsenic a suspect.

Not agelong after, US Marshals joined the lawsuit and learned that Pan's household had entree to millions of dollars successful assets.

Pan was inactive at-large and investigators disquieted helium mightiness beryllium trying to fly the country.

'This became truthful precocious illustration truthful fast,' US Marshal Joe Galvan told 48 Hours. 'It was conscionable heightened.'

When asked of his whereabouts, they said he'd simply gotten retired of the car and walked away, and they didn't cognize wherever he'd gone.

'They would spell to the ends of the world to assistance enactment and fell him,' Matthew Duffy, a supervisor of the US Marshals Fugitive Task Force successful Connecticut, said.

Investigators past shifted their absorption onto Pan's the parents, hoping they would pb them to their fugitive son.

The protective parent made a telephone telephone from a edifice utilizing a clerk's phone.

Investigators tailing the fear-stricken parents aboriginal spoke to the clerk and were capable to way the call, yet starring them to Pan's determination astatine a boarding location successful Montgomery, Alabama - implicit 1,100 miles from the New Haven transgression scene.
