Investigators say a 72-year-old homeowner was killed when at least two masked men entered his home in an apparent robbery in the 10800-block of South Sangamon Street in the city's Morgan Park community.
The victim's adult son and another person were also in the house at the time of the home invasion. They were not injured.
Area 2 police detectives were questioning three people that officials are now calling persons of interest in connection to the homicide.
Investigators say Anglin was killed when at least two masked men forced their way into his home around 1 a.m. and ransacked the small, brick home.
Anglin's younger son tells police his father was shot in the chest as they and another person in the home tried to flee. Cassandra Jackson says her grandson heard the commotion.
"He said that Langford, which is Mr. Anglin's son, came and knocked on our door and said, 'call 911,' that his father had been shot," said Jackson.
But before Anglin died at the hospital, officers, who were unaware of the attack, responded to a burglary in progress call several blocks away and stopped and eventually arrested the occupants of a car driving without their headlights on.
Police say all three men had black masks on and one of them had thousands of dollars in cash in his back pocket.
Friday morning, as officers still searched for the weapon used in the attack, neighbors say there've been many break-ins recently.
"Basically, this neighborhood has gone to pot. The way I consider it, it's gone to pot," said Darryl Anthony, neighborhood resident.
Meanwhile, friends and family of the murdered man remember him as kind and generous.
"Surprising. Very nice guy. Doesn't bother anybody," said Rowlanda Jackson, victim's neighbor.
A father to five adult children, Anglin was a retired Chicago city worker who had lived in the Morgan Park neighborhood with his wife for over 40 years.
"He was a loving father. Always tried to make sure we had the best of everything, a hard worker, just an all-around good guy," said Norman Williamson, Anglin's son.
The loss is especially difficult for Williamson who recently lost his wife to breast cancer.
Anglin's wife was not at home at the time of the attack. She was out of town.
No charges have been filed.
