A 33-year-old Pennsylvania teacher who was shot dead outside her mother's house was the victim of a 'crime of passion', investigators have said.
Rachael DelTondo was killed by a hail of bullets on Mother's Day - just months after being suspended from her job when a police report was leaked revealing she had been found in a steamed-up parked car with a 17-year-old boy.
Cops said they are investigating 'everyone that was driving' near the crime scene in Aliquippa on Sunday.

DelTondo's death comes just six months after the Pennsylvania Cyber Charter School teacher was suspended from her job over a leaked police report
Beaver County District Attorney David Lozier said prosecutors 'could not be taking this more seriously', CBS Pittsburgh reported, adding that evidence appeared to show the perpetrator was known to the victim.
Meanwhile they have been scouring security footage and are attempting to access DelTondo's phone.
DelTondo's death comes just six months after the Pennsylvania Cyber Charter School teacher was suspended from her job over a leaked police report.
School officials and members of the media received an anonymous email in October 2017 containing the 2016 Aliquippa police incident report which implied she inappropriately met with a 17-year-old boy, Times Online reported.
The report stated that officers were on patrol at around 1.50am on February 6, 2016, when they saw a car parked near the old Aliquippa Hospital.
Police noted that 'the windows were steamed over and the engine was not running.'
Inside was DelTondo and the teen.

DelTondo reportedly told officers at the time that she was talking with a 'former student.'
However, School CEO Brian Hayden said records show the teen was never a registered student at PA Cyber. Cops later found text messages and Snapchat messages which revealed the pair had a 'relationship.'
Lozier said this exposure was a 'personal vendetta against' DelTondo.
He added: 'It's shameful that this woman was painted with a police report that had been written that did not result in criminal charges.'
During the confrontation with officers, DelTondo reportedly told police that she and the teen were 'friends' and that they were 'just talking' because he was 'upset'.

She also said 'she didn't want her fiancé to know that she was here parked because he would get mad.'
No charges were brought against DelTondo over the incident, and police drove the teen home that evening. The report was not public knowledge until the anonymous email was sent in October last year.
The school announced they were suspending her the following month.
The leak prompted a state police investigation by Aliquippa Police - which DelTondo complied with.
Brian Hayden, chief executive officer of the Pennsylvania Cyber Charter School, earlier released a statement after learning of DelTondo's death.
'We were saddened this morning to learn of the tragic death of Rachel DelTondo, apparently the result of a violent incident in the City of Aliquippa.
'We have no additional information beyond what is being reported by local media. We express our sympathy to her family, friends, and coworkers. Ms. DelTondo was employed by PA Cyber but on a paid suspension.'
The death has stunned neighbors in the quiet neighborhood and police are hunting for clues to the identity of the killer.

'I counted six shots that I heard,' a neighbor, Fred Poore, told CBS News after the shooting.
Earlier last year, DelTondo was in the press over a dispute with a bridal shop over her wedding dress.
The teacher was planning a big, elaborate day with her Italian-American family, which included a $10,000, custom-made dress from a New York designer, CBS Local reported.
But the wedding was called off a few months after DelTondo was caught with the teen, but before the report was made public.
The family, who had already put down a $4,600 non-refundable deposit, told the salon they would like to pay the balance and receive the dress so they could sell it, but said the designer never delivered the gown and refused to refund their deposit.
Eventually, they took the salon to court and got a local investigative reporter involved to pressure the wedding dress maker into doing the right thing. By early 2017, they finally received a check in the mail.
Today, family, neighbors and friends are struggling to come to terms with her sudden death.
'I don't know why that happened. I really don't,' said Dan Casper, a neighbor, who described the 32-year-old as a 'beautiful lady, friendly, knew everybody, talked to everybody'.
DelTondo had just returned from getting ice cream on Sunday evening when she was shot dead.
The Beaver County Coroner's Office has ruled DelTondo's death a homicide.
