The man identified as a suspect in the killing of a 93-year-old Philadelphia man is now in custody.

Coy Thomas, 53, was arrested Sunday for the murder of Lafayette Dailey at 22nd Street and Lehigh Avenue, Philadelphia Police said.

Dailey's body was found inside his home on the 4500 block of North 16th Street around 3 p.m. on Dec. 5, according to police. The Philadelphia Medical Examiner's Office later determined Dailey was stabbed to death.

Police said Dailey's Chrysler sedan was missing along with his car keys and wallet. 

Investigators said Dailey's niece received a phone call from a neighbor on Dec. 5 letting her know her uncle had not been seen for about two days. The senior center Dailey regularly attended had also reported he had not been there.  

Thomas was identified as a suspect in a news release on Friday morning. Surveillance video shows a man, who detectives have identified as Thomas, walking onto Dailey's porch on Dec. 3 and then driving away in Dailey's car about 10 minutes later, a news release from the Philadelphia district attorney's office on Monday said. On Dec. 8, detectives were informed that someone was using Dailey's debit card, and police found the Chrysler sedan on Dec. 9. Later that day, someone called police and said they bought the car from Dailey for $900, according to the DA's office.

Thomas faces charges of murder, robbery, theft, unauthorized use of a vehicle and possessing an instrument of a crime, the DA's office said. A preliminary hearing is scheduled for Dec. 29.

It's unclear whether Thomas and Dailey knew each other.
