Lubbock Police found 32 year old David Martinez stabbed in the 3000 block of 35th Street Wednesday afternoon.
Police arrested 35 year old Joshua Bulls for his murder.
KLBK found Friday that Martinez and 32 year old Jodi Winn were Facebook friends. KLBK brought this information forward to police, which they had not known before.
Police found Winn dead in her home in the Fort Jackson Mobile Home Estates Wednesday night.
KLBK also learned that Martinez was Facebook friends with Bulls.
Neighbors KLBK spoke to Friday say they also have reason to believe the two murders were connected.
When LPD was asked about a possible connection between the murders, Police said that it is still early in their investigations.
Two bartenders from Fast Eddie's said they regularly served Bulls, and were shocked to hear of his arrest. They also said they last served him Tuesday night, and noticed he was acting differently. "Wouldn't you say that the last day he came in, he was normal, which was not normal, you know?," said Meagan Petty.
"He was quiet, real quiet, didn't talk to anyone, didn't even sing to himself, he just sat there and stared off into space," said Petty about Bulls behavior.
